It's a fun game to spend time on! I especially like the way it auto sorts. I missed a lot of obvious moves but got carried by the hint system
I won my second game by saving nearly all my jello. The problem with using your health as currency is that you have to make everything you spend it on extremely valueable to be worth it, and none of the items seemed to be worth it
In terms of roguelike-ness it felt very one-dimensional since everything was based around one special move
There's not a lot of feedback on spending/gaining jello so it's hard to keep track of your balance. I'd suggest also adding SFX on hovering over cards and when jello are pushed/hovered/clicked on for immersion's sake.
I didn't like the tentacle cursor, something about it is less intuitive for where you're clicking than a normal cursor
I think 'Jello' is trademarked and kind of an unsuited name even without the association to the food considering they're jell-ee-fish, Jell-ee-taire, etc.
