Glad you liked it! The game has a bug where you can use the level-up perk shortcut (S or D) even if you don’t have enough XP.
Spoiler
Without using this bug my best score is 37 eyes, the slime has a spell that allows it to gain a level. You can then kill it to get the XP back.I ran out of time during the game jam to make the third level, after the rating period has ended (in ~2 weeks) I’ll update the game with bug fixes and more content.
