Here's an idea, when hovering the mouse over upgrade tiles, they should highlight, when clicking, they should go in, or highlight a little more. Right now it kinda makes you feel like you aren't clicking much ...
I agree with Shark4675's comment, there should be death match and a team death match, it would make this game much more cooler. This game has a lot of potential if the developers would just listen to us.
@iceboy You CAN move buildings - click on 'Build' and then on the right, under rotate, there's a small icon with four arrows pointing outwards. If you hover your mouse over it you can see it's labelled 'Move', click it and click on the building you want to move.
I definitely think the Pepper Grinder needs more damage, it costs 35 more tokens than the Tommy, yet the Tommy's stats are better in terms of accuracy, damage, capacity and fire rate.
You'd think that, wouldn't you.
