Man I'd really like to see this finished, the art and animations are awesome! and the concept works quite well, it's a good bit of fun to play even in it's current state. Only thing I'd really note is that it'd be nice to have the arm retract towards the body when the cursor is close to it so you can hit enemies that get too near to you, this becomes especially problematic as you grow in size, it'd also be nice to have a bit more feedback on the growing as you slowly gain in size before you transform. Hope you keep developing this thing out! Great work!
