hey, guys... stop...
critique is important, yes... but in the end it's still Kenneth who has to decide how to do it all.
The game isn't perfect, but it's not done yet, either... I would work a bit on the sprites, Straight_heart's right in that. If you wanna sell this game, good sprite's a great way to make it look a bunch better. But the game idea's good, and I'm sure you have spent a bunch of time on the game. So, just keep it up!
