Nice concept, but:
1)No save = thatss BAD
2)No 1-2 sec invulnerability after being hit = very annoying
3)Mobs spawning at your closest vincinity - I hate this one - a black hole appeared right under my ship once - c'mon, what was I supposed to do? Another example - mobs spawned all around me = instant death = instant 1/5
The game itself looks very nice and the upgrade system is very nice, but cause of many annoying little (and big - like those stated above) make it very unpleasant, if not unplayable.
1/5
