Yeah I think the levels are a little loose and the difficulty curve is very steep currently cos I didn't have a ton of time to design more but they are all completable, it's a matter of getting the order of execution right, so for level 2 for example, the trick is to kill the slime first but stay with the rat, bleed the human and then either avoid it until it bleeds out or let it kill you and THEN reap the slime while you wait for the human to bleed out.
I'm currently reworking some of the levels so when you get stuck it's a lot more obvious that it's not a bug, and adding a few more progression levels to hopefully guide players into being more aware of those tricks before throwing them into a bigger level x3
Thank you for playing! Hope you'll play again when I upload a new build after the voting period ends.
