I give up for now, lvl 58. A few toughts: 1. put stats for weapons: damage, recharge time (sec), shots/seconds per charge, better description. 2.put life on lower bar, there is a space next to weapos (you don't have much anyway). 3. put a delay on enemies, if you can't move they can't shoot either, some lvls you star already suround by bullets/enemies. 5. the extra 5 seconds hurt you more than helps, make you invincible or if you die you don't the any bonus. 6. make enemies take little longer to ge out of the "hole", some times there is not enough space to maneuver and you could use that route for a moment and is a cheap way to lose life as they pop beneath you. 6. make enemies come out from "holes" or from outside the screen, NOT both. Not to mention you can't replay lvls and how insane some bosses are. PS: WTF bomb is annoying as hell!
What I really don't like is having to shoot by pressing the mouse button, but good game, add a few other upgrades and weapons and it could be a great one.
