Thanks a lot! Difficulty balance might indeed be not too good in this build I kinda did the level design quickly without going back to it afterward too much! I'll definitely polish that up after the jam and add a bunch of new levels :) 

That blob can be quite tricky when you don't get it but there's alternative solutions, I'll put some other rooms before so it doesn't feel like unfair difficulty! 

Adding health, at first I thought it would be nice to make the game more friendly, however I realised it would break the feel of the game in most cases. Like if you get hit aren't you supposed to get knock back? But then wouldn't that make you go back even tho that's the whole point of the game, not going back? Also when your on the same horizontal line of an ennemie, you know you can't kill him anymore, which makes it really important to always stay behind an ennemie if you want to get him out, but by adding more health that wouldn't be a problem anymore, not to mention you could just breeze through most rooms that were puzzle based at first :/

So yeah I wouldn't know how to fix that, I think no health is fine since the rooms are fairly short but yeah I wouldn't want my game to be frustrating.
