Good game, two comments. Don't need to see the cut scenes on replays and don't make your powerups look like the bullets. Make one of them red or something.
one gameplay suggestion. i build vs. ninjas. everything else is incidental. Reduce the invis duration by a second or even two ( if it works). I'm writing this in between ninja raids if that helps make the point.
agreed. has that wow skilltree feel, needs the reset to go with it. i guess its short enough a game that i can just start over, but.. also, seems like a perfect game for some real badges. Not gonna say it's better than gemcraft, but f'in solid. I'm givin it a 4, but a 5 if you make these adds.
