Super fun! I really like this concept - it's creative, funny, fun to play, simple, and realistic. What a great idea!
The gameplay was also very fun, it's so much fun gobbling up the hordes of mini organisms as you stomp around as a monolith. I also really liked the art and music too, and felt that they fit the game really well. The art style was consistent through the menus and the game assets, and the music flowed well and never felt too jarring or quiet.
I think the game should be more punishing if you smack into larger organisms. Throughout the first level, I think I rammed into larger blobs several times, but not much seemed to happen. Also, the controls were a little funky, but nothing too drastic.
This is a really fun game! There is a ton of character and personality packed into this entry, and I'm really impressed by what you've accomplished in just 48 hours!
