Tryrush Deppy. It's a Sonic-like, getting to the end of the level is easy but finding all the secret routes and stuff is hard. However the difference is that you can't backtrack so you only get one attempt in most cases to find the alt routes which can be infuriating. IIRC you can save between levels at least
