This is a bootleg Donkey Kong Country game for the Genesis, using assets from all three SNES DKC games, and using Mario music for many levels for some reason.
You can't roll at all. Getting shot out of a barrel gives you a lot of speed. Diddy Kong is completely missing, so you'll die in one hit.
I started testing the game a bit more, and when I collected a KONG letter, the game froze. When I tried recording this happening, the game kept playing just fine, so I don't know what's going on there.

I thought that was a bug with the Genesis Plus GX core on BizHawk, since on BlastEm, Gens and even Kega Fusion, no game crash occured after collecting a letter. But I don't know anymore.
If anyone's ever going to make a TAS for this game, please keep this potential issue in mind.
