Are you kidding? He quite literally infinitely expanded the game with Endless mode, redesigned the upgrade system, added an entirely new mechanic, and gave us Spider-tron 6000. What do you mean "didn't add anything"?
As for the "not taking ideas from the community", what do you expect for two weeks of exposure? The "suggestions" section is, as the name implies, for suggestions. I'm fairly new to coding, but I'd bet a lot of what in there (namely, new weapon ideas) would take a ton of re-coding, much less implementing.
