Fullscreen doesn't seem to work, and I got lost with the objectives. Seems like a rogue-like game where you pwn monsters, stopping them from spreading corruption seems like...? The music was nice together with the art style.
The movement looks twitchy and SFX for attacks would have made a big impact on the immersion. There are other bugs and I didn't quite get the corruption idea (you kill people and then demons have spawned in someone's yard?), but my favorite part is definitely the pixel art.
