Enjoyed some of the levels in this. Particularly liked the level where the player basically goes through twice, once without "weight" and once with it. There are some good concepts in here.
The hitboxes are the biggest setback right now I would say, along with visual variety. The hitboxes do not appear to match the sprites they are connected to, and it was hard at times to tell where exactly I was safe and where I wasn't.
A good start, excited to see what's next!
