There should be acceleration and deceleration variables, so that movement is more fluid. Otherwise nice game, it could lead to something great.

Baffled, as always, in the apparent utter faith game designers have that vanishing rewards makes for an enjoyable or popular game mechanic. No progress bar for leveling, so uncertain as to timing. No statistics given for any powerup, so uncertain how much good that is doing. Enemy durability rapidly progresses to the level where constant weapon power increase feels like 'running in place'. Interesting music and simple but appealing graphics, and snappy controls keep this in the 'frustrating almost-good' category. Better luck next time!

I'm not sure if the attack upgrade works... for example the purple enemies need 2 hits and they still need 2 hits after i upgraded attack about 4 times...

The game starts out alright however it gets boring fast due to no stats like Anrichan says and the enemy movements like afklol says. I would also add that having extra sounds for the weapon or enemies would make the game more immersive.
