The premise is odd but could be interesting.
In the settings menu, it would be nice to have background on the values. Music and some of the controls become hard to read depending on the position on the screen.
Visually it was alright, although, I really enjoyed the effect from the menu to the game, nice effect between scenes.
The music felt a bit... unfitting? A bit too serious for something this cartoonish. The jump sound effect could be a bit shorter, gets annoying fast.
I couldn't make it past the first level, didn't understand where was I supposed to go. I seemed to reach the end of the level and got a crystal, but nothing happened after that. Also it's a bit odd to respawn after dying but all ants are gone up until where you died. It does makes it easier to advance but it feels too empty. However, really nice touch to add some unexpected things like the moving spikes and the ant laughing when it kills you, that was really unexpected and it was fun! Once I killed an ant that gave me a new heart or something like that, didn't quite get what changed.
The hitboxes make it harder than it should be, I collide with platforms while not even being close to them, it's hard to figure where can I position myself for jumps.
It's a neat little platformer that could use some polishing in collision detection. Also more unexpected events to make use of the silly premise.
