I really loved Spore - especially the bacteria and first land phase, where you got to really build you organism like you'd fantasize.
And I felt the same vibes here - naturally I loved it too.
Especially since the level ups are very quick, so you get to test all the different power ups.
I had some problems with the boss fight - which caused a bit of frustration.
1. I leveled the Dash Ability - since it damaged/killed smaller cells I thought nice, Ill make that my main damage ability, but learned that I took damage dashing the boss. I mean this was also a bit on my part because I just later discovered the "hurt"-phase of the boss.
2. But by the time i realized that, I pushed im in the upper right corner, where the way continues, causing him to get stuck... so I couldn't get behind him and get those two hit zones.
Regardless of this I had TONS of fun this won't affect the rating for your amazing game.
Congratulations on finishing your first game jam submission with such a great entry.
