I like the simplicity and the music adds a lot of charm. I think it would be nice if it had more levels, and if the player had something to do while the ant was crawling, (e.g. holding space to slow enemies slightly, or affect the environment in other ways so it's not just about timing the inputs). The cutscene at the end was also nice!
Yes, you're right, this game in its actual form is very (too ?) simple/minimalist. I know I could add more things like speed changing or direction to choose, and more different levels. But it's only a gamejam project made in few hours, so I focused more on the music (it's my job) than the rest of the game (level design, gameplay, ...). If one day I want to make a bigger game from this gamejam project (but it's not my actual priority, to be honest ^^), I'll create my own graphics and do better variety of gameplay, ennemies and levels, with a lot of funny and cute cutscenes. Thank you for your nice and constructive comment ^_^
