Thank you so much for the detailed review!
Having the objects drawn at each scale was basically essential for me, since when pixel ratios are off it bugs me a lot... But it definitely became a lot of work to animate each size the player, ballista, and arrows.
I'm glad a lot of people got the hopes met with scaling the player, I wanted to have a sense of "oh, I bet / hope I can do this", then fulfilling that.
I did try to have each scale serve a purpose, and I do still think there needs to be some more things that makes them more distinct or useful. Making the player gain different attributes was fun, but i definitely made the small player a bit too op with its size, which made puzzles harder to design...
I've already started work on a post jam patch that'll fix some of the weird hitbox size decisions I made, and the scale projectile was one I increased, since it doesn't do any harm being larger.
