Armello is a video game board-game sort of thing featuring furry characters. The game's lore and world is pretty stock-standard fantasy fair besides the animal people, but has some nice quirks to it and a theme of good vs evil. The thing about Armello though is it has rules for dice, combat, and stats for characters since it has some RPG elements. For this reason I sometimes consider how Armello could be used to create a system for tabletop RPG adventuring- and I wrote one up.
If you converted the level up system for a to-gold traditional system, you could probably make this an OSR style game about cute animal people getting fucking murdered in dungeons.
But I'll leave that honor up to you.

Armello Dice Symbols
Armello uses regular 6 sided dice for their rolling mechanics, but without numbers and instead symbols. I've linked these up to numbers on a die that I think are very close to their original symbols and intent, plus each piece is on the exact other side as its opposite.
Armello uses 4 stats; Health, Fight, Wits, Spirit. Health is the number of hits you take before falling; a single combat may not kill you, just the total number of injuries over time exceeding your health will. Fight is the number of dice rolled in combat, Wits is the number of dice used in perils, and Spirit is the magic stat. All characters in Armello itself start with a stat total of 15, you could adjust these numbers. With a recommended soft cap of 5 in one single stat.
Combat in Armello deals damage both ways, both attacker and defender can die from an attack. But combat in the board game is about an entire exchange, not blow by blow, which would work better for this system. The problem comes with party based gameplay, how are multiple characters supposed to contribute to one battle? Maybe they do not, or maybe each exchange only counts for a single few seconds of dueling, but is still an exchange between a target and yourself either way. Maybe everyone in the party just rolls combat, is hit with an enemy 'force' die roll, and hope they overcome it. Here is a small bestiary.
Every Sword is a hit. Every Shield is a block, which blocks one enemy hit.
In Armello, Suns count as hits during the day and moons at night. Due to dungeon crawling usually being a big aspect of OSR, this applies a lot less. Instead moons count as hits when you are sneak attacking, and suns count during pitched combat. Maybe instead it's based on light; Suns count as a hit when you have enough torchlight. Maybe moons count as a hit if your light level is as low as it can go, or only counts as a hit for those with Infra-vision.
Then, there is Wyld and Rot dice. Wyld and Rot dice count as hits in combat if you're the right alignment, and they explode meaning after registering it as a hit it rerolls again. The opposite alignment die just counts as a miss.
Wyld die is explosive and powerful for characters who are lawful or clean of the Rot.
Rot die is explosive and powerful for characters who are choatic or corrupted by the Rot.
Armello Saving Throws & Skill Checks
These are called Perils. The DM rolls a certain number of dice, and you need to roll the same symbols. You roll a number of dice equal to your Wits stat, with a die of your alignment counting as a reroll. Even if one of the symbols of the test is your alignment symbol, you still receive a reroll after it is 'locked in'.
You have a number of spell points equal to your magic stat. Each spell point can be expended to cast a first level spell effect, or can be combined to cast a higher level spell effect. Your magic points only return at dusk. Most spells and magic in Armello have a curse/buffing or healing effect and are almost always tied to nature and natural forces- such as letting out the inner beast of each of the anthro characters, healing rot corruption, or calling a lightning strike on a foe. Either make up your spells as you cast them or the DM will make some spells for you with appropriate costs.
Spells directed at enemies get a save; the number of die rolled by the caster is dependent on their magic stat vs the wit dice of the enemy getting hit regardless of the number of spell points used. Characters high in Spirit will have weak spells that are hard to resist from their sheer force of will.
You could also substitute something akin to the Sage magic system; with each magic point being equal to 1 HD of 'power' you can use for a spell. The magic system can be vague in the game, being tied to cards that you can play. For this you can divorce it from the setting and make a more general magic system with less nature-based effects to tie it into your setting instead.
The final type of magic are Spirit stones. Spirits stones are a general collection of Wyld power. Each spirit stone can be expended as a one time 1 point magic boost to cast a spell with or to empower another spell. It is said collecting 4 spirit stones and performing a ritual can totally cure a person corrupted with Rot, but this will result in the person's death if they are truly evil on the inside.
This is a maddening disease that slowly corrupts and kills those infected by it. It is a perversion of nature and bringer of ruin. Banes and other creatures deep within dungeons have the rot- and can spread it to characters by defeating them in combat. Once infected with the Rot, the character takes 1 point of damage each sunrise.
When a character has 1-4 Rot, they are considered “infected” by the rot. At this point, they can, if willing, roll a number of dice equal to their spirit and spend 2 magic once per day when sitting at a place of natural beauty. If they get at least enough Wyld dice equal or greater then their rot, they can cure 1 rot for that day. This is one of the few ways to heal rot, the other methods involving rare potions and talismans.
Once a person reaches 5 Rot though they are considered Corrupted. Their body starts to change; and while they still take 1 damage per day at sunrise, the rot gives them power and they start to depend on it. Rot dice now count as wild and the Wyld dice count as useless rot dice in combat. Additionally, once a character is corrupted, anytime they fight a character with any amount of rot less then them, they get to add a number of dice equal to the lesser rot character's rot stat. Therefore a character with 5 rot gets to add +2 dice to hit attack against a character with 2 rot. This also applies to magic saves.
Prestige & Leveling Up
Each time you complete a general quest objective, solve a worthy challenge, or defeat a creature of darkness you get +1 prestige. Prestige is the closest thing Armello has to a social mechanic; so assume characters with higher prestige have more sway with commoners, nobles, and the various factions in the lands of Armello.
Each time you complete one of these major quests, you also get a level up. You may select any stat to increase, and gain that benefit permanently. You cannot choose the same stat twice in a row, and can level up a maximum of 4 times.

 The rot has spread to a small and sleepy town- and as the King's Guard fight to keep it contained it spreads. Then again, and then again. The corruption of both mind and body is seemingly spreading among the population, one step ahead of the law.
