Really cool slime mechanics! And well done on having the tutorial as part of small levels..always great to see that!
Having your body in the place you lose is a nice touch allows the player to risk more exactly as the jam theme want it :D
Suggestions;
- Opening and Closing the Spin Panel with E is fine but consider adding a close btn or bind it to ESC for beter UI navigation.
- After the basic tutorial lvls are completed the player could start on the lost lvl again instead of the very first...or at least at the first lvl after the tutorial to encourage him to replay the game and keep retention.
I can really see that game being also released on mobile!
Well Done!
