I dig the aesthetic, somewhere between cute and unsettling. The plinko/pachinko mechanic is also neat, I can imagine dealing with really complicated layouts would be fun (in the frustrating kind of way). Couple notes though:
- Did you intend for the ant player to roll around? If not, you should lock the Z axis on the rigid body.
- I noticed some sticking while scooting the ant around. Are you using a tilemap to render the non-oblique platforms? If so you should check out the composite collider
