Really cool game! It's remarkable how long it is considering it's a jam game, and it was really cool to see your abilities actually progress from using the platforms into being able to control the scaling yourself. I feel like most jam games don't have the scope to add things like that and it was cool to see. Great work!
Just as a quick heads up, I did encounter one weird bug- for some reason, when you're using the arrow keys, the game doesn't seem to be able to recognize more than two inputs at once- so if you press the up, left, and space keys all at the same time to try and jump to the left while scaled up, one of the inputs gets lost every time. Luckily it works completely fine if you just stick to using WASD. Just figured I'd mention that so you'd know/ so future game jam people know to use WASD!
