Meh..
Graphics: Simple, clean, a very good representation of a world facing a cold weather apacolypse. Everything looks great :) 3/3
Sound: Good sound effects and music, but not much variety here. The same sounds get old after a while. 2/3
Execution: Definitely a challenge, but once you get use to the way the pattern goes core #3 is the only real challenge here. The biggest challenge is how frustrating the game is with one hit kills. I understand it is meant to be hard, but there is a challenge between hard and frustrating. Even if you only had 3 hit points, so that if you make a dumb mistake you aren't counted against by having to start the whole damn thing over again. 0/3
Overall it was fun for a while, then it was frustrating, and the in the end not very satisfying. Just another good looking and outstanding space shooter that is hurt dramatically by a lacking of lives/hit points and checkpoints.
5/10
