Oh, and by the way? Falling through the dinosaur's head and having either character getting shot through the ceiling occasionally on a spring? Those aren't minor bugs. Fix them.
Annoying glitch: When you lose a bubble, all the bubbles that came from that bubble will take over other bubbles in that color, so if you have blue bubbles heading toward a gray one, and your bubble was taken by red, the gray bubble will turn red. This is inexcusable, really.
The black puke is where the game's controls are clearly lacking. It's way too easy to slip and fall, and sometimes you fall THROUGH the puke. It makes an otherwise enjoyable game more frustrating than need be.
Such a sloppy execution. Add auto attack, add building killing potential for the player, and fix the overpowered aliens and underpowered marines and then maybe I'll change my rating.
Fix the controls. My only real complaint beyond the fact that the upgrade description tends to stick in the way after browsing it. Good game otherwise.
The lack of hotkeys leaves something to be desired, especially given the frantic button mashing of the next wave button. Hotkeys for the towers and the next wave button should be implemented. Otherwise, an alright game, although the uselessness of the Fast and Multi Fire towers is ridiculous.
