I mean, the game is ok (nothing remarkable but not bad either), but I think we have to be a bit more strict with the definition of "incremental". This is clearly a Tower Defense game, it has all tower defense elements, but I don't see any incremental elements (specific from the incremental genre) on it. Sure, it "increments" but all tower defense games increment, you upgrade your towers, you upgrade your boosts...

My point is, what makes this game different that it deserves to pass the filter to be on this site, and that other tower defense games don't have?
