I liked the concept for this and the presentation is really good.
The difficulty of the game made it tricky to really get into. Because Jelly is so bad at killing enemies, there seems to be more and more of them with every second, until there's basically no open spaces for me to jump to anymore. I'm sure that it could be done if you're very good, but the lack of progress I was making was pretty discouraging for the most part. If Jelly could deal with enemies a bit fast (the 50% damage bump helps, but not enough), it might have worked. I also would have liked to see more upgrades for Peanut, other than the extra jump (if there were some of those, I never got them), to make survival a bit more feasible.
Overall, I think this is a pretty polished game (except for one or two small bugs), and it looks quite good as well in the sort of arcade aesthetic.
