Electronic Super Joy:
Groove City
In this sequal you're fighting against a robot who's angry because Dr Swinger stole her Laser Nipples. You gotta help the robot and defeat Dr Swinger! Because... Laser Nipples!
This is the sequal to the game with the same name. It's a difficult platformer that looks really good and has a nice sound to it. The atmosphere is kinda nice as well and there are citizens that give you hints while you play.
It's no my cup of tea so I shall refrain from further comments.
Verdict: If you're into difficult platformers than you should play this game, and its predecessor. The implementation feels solid, looks pretty, sounds great, and there are plenty of hard to get secrets to be found.
Familiarity: Not played before (nor its prequal)
