No Great Name
Arcane
The first game I looked at from that link is as you said an arcade shooter. The video was hilarious.When you say that you are not swamped with several nearly identical titles*, you are not paying attention (which may be good for your sanity). I had already linked to the current line-up of the Groupees Greenlight. You have standard arcade shooters, tower defense and Bejeweled clones. It's the same stuff over and over, just with a fresh coat of paint.
"Dodge the bullets" at 0:55 and "Cry on epic story" at 1:16 are the definite highlights.
