Beat the game at 4:04 by destroying the enemy base. There are some issues I would like to present:

- Most of the audio is repetitive. You may want to introduce pitch variation to reduce the effect.

- The gun gets louder each time it gets upgraded. By the time I reached max level, it was far too loud.

- The gun fires as fast as you can press so it makes it easy to cheese the enemy base by just clicking really fast.

- The movement animation for the player character seems to have some artifacts near the feet.

- the enemies died and exploded with look like particle systems. The particles should fade over their life so they don't seem to disappear instantly.

Besides these issues, I would like to say the game could still be very good if some improvements are made.

The core of attacking the enemy base while defending your own, coupled with the upgrading of weapons is cool. The main thing you could improve would be the feedback, for instance when you shoot the enemies there's no reaction until they die. Would be good to see you do more with this.

you know its fun. But at some moment your hand gets tired . You should make gun automatic at least starting from 2 or 3 level....I cant feel my hand! 

Neat game! Cool looking player character.

I have to agree with Paul... an auto-fire feature would help. Other than that, cool app. ^ ^

Good idea, could use some autofire tho. If i tap left mouse button with my left hand's 2 fingers it becomes a submachine gun like lol. But at the same time I can't move then
