It's got potential, but not nearly there.
The idea is pretty cool, I'd even go as far as saying, even kind of original.
But the game has it flaws. First of all, it's pretty hard, I couldn't make it past level four even thought I was trying my hardest, and was taking some pretty cautious measures.
Second, the game command freezes at times. Usually when there's a lot of action happening. And I don't think it's my pc, since it always runs perfect.
Third. What's the idea for not seeing the enemies until they're really close?
I think it would make more sense, if you were able to see the enemies if they were on the field of vision. That's logical, + enhances your chance of survival.
I also think making YOUR character faster might make the game easier and more enjoyable. Also some powerups along the way, might be a good idea to keep interest.
That's it.
