A very early PC-98 game published by System Sacom. You play a googly-eyed monster which tries to eat blue dots while avoiding red dots. Unfortunately, while the dot fleeing is really well modeled, the game itself is kind of sketchy, as it uses tank controls for your character, who easily gets stuck on edges. Making things even worse is that the dots can move through the darkness, and you can't.
This game appears to have some kind of graphical glitch with Virtual98, and jams after a pretty short time on Anex86, so I'd suggest running it on Neko Project.
