Really sorry I didn't get to your game during the feedback stream! In lieu of that, I'll post my feedback here.
1. The player starts out moving incredibly fast. It makes it super easy to run into enemies spawning from your direction of movement before you have a chance to react.
2. Some of the costs are substantially more punishing than others. For example, losing your health is way worse than losing half of your vision- since you can still see! Not having control over what you lose makes this issue even more evident, since it often feels like you just need good RNG to win.
3. I love the theming, aesthetic, style, everything about the game visually! I think it's got a lot of charm and pulls its spooky setting off spectacularly. The music also works well, and the Lich's robotic "ha ha ha" helps to sell the whole package. I just wish the sound effects were a touch punchier/weightier.
4. The game fits the jam theme very well! I like how in this game, "cost" is interpreted less as a numerical value and more as a concept, leading to well-thought-out (if not perfectly balanced) debuffs.
Overall, I enjoyed playing your game! It's very impressively polished for such a short time frame as well!
