Very nice art. Both the 3D visuals and the 2D cutscenes. The slug character is very funny looking, lol; I think I might have nightmares.
The music is good and the SFX are nicely implemented. Death is a bit confusing. You can keep playing and the screen takes forever to fade out while you do.
The rolling around mechanic is neat and sticking to the walls and ceiling is a very cool mechanic, I've not seen before.
The boss attacks are nicely varied and the lock on system greatly needed. particularly, for the first boss when he went underground.
Nice submission.
