It's a really neat little deckbuilder, very easy to pick up and play. The presentation is particularly impressive - I love the old school 3D vibe!
I think a few people below have mentioned that it feels too luck-based, and I have to agree. Most of the damage I took was self-inflicted, which doesn't feel great as a player 😭 A quick fix would be to make the corruption chance ramp up more slowly, but the fundamental issue is with random chance - every card has an increasing chance of actively hindering you! If you take a look at Pokémon for example, Fire blast/Hydro pump/Thunder/etc are all used less because of their negative effect. This is now every attack in the game!
I don't think it's necessarily a bad mechanic, I just want it to be explored further - I am imagining self harm builds that give massive buffs when you're corrupted! High risk, high reward type stuff. Or other builds that mitigate it - I want more control over that chance, then I think it will feel better.
