- Got a game glich which killed me when I had 12.2.
- There should be a pause button.
- There should have an impossible badge at 15 or 20.
- The games shouldn't start from where they stopped; it makes them impossible in some cases.
After gettin' the hang of it, it becomes easy: just don't bother about life energy or whatever... survive till level 6 to earn enough points to get the antimatter shield and then survive again until you can get the heatseekers. Until and after that, just keep getting more interest and keep buying energy infuser so you can get to kill the tanks and finish the game faster (it took me less than an hour).
Bad game. 2/5
