Great pixel art!
The jumps in the game felt really strange, for example, when you are jumping with the full robot, you could barely jump, I like how the legs jump higher (as they are the legs), but it brings out the second problem with the jump, as it is inconsistent, which is due to the jump setting the motion instead of adding to it, witch can be a good idea, but with the air time, it leads to vastly difrent jumps, and not being able to tell how high I can jump.
But I know you couldn't have polished the jump as much because of dev pain with the splitting mechanic sooo yea. relatable here, I had to add a timer that prevents you from jumping in my game so you wouldn't fly, so :P.
But overall a great game with great pixel art and levels :)
