I’m sure I’ve played a different time in my life but took focus of
SOCKET by Vic Tokai or Time Eliminator First in Japan. It’s a Sonic Clone through and through. You have no extra momentum method so I got stuck a couple of times on a ramp. The levels are very twisty turny with dead ends.
It looks very Megadrive to a fault and just sort of reads as visual noise. This gets worse if you turn on a CRT filter.
Despite there being individual stage hazards they lack individual identity and again just turns to mush in your brain.
Not a great Sonic-like, but also rises to the top by default ok the megadrive. I actually like High Seas Havoc though.
