Good game, impressed with the amount of content you managed to make.
Small nitpick, when introducing the shooting, make it more obvious you have to aim at an object
Maybe make the green elevator stay scaled for the entire trip
Appreciate the volume slider, wish I had time to add it to our project
Conveyors launch you very far if you shrink it instead of grow it, is that intended? it feels unintuitive
Respawns can get frustrating on harder sections of the game, I would make them faster.
You could make a full game out if this if you wanted to.
