The positive: This was a completely new concept while still being a super cool retro style space game. It was also a really cool concept. I could see getting really good at the game and going super fast and having a really great time. The artwork was near perfect. The music actually was perfect. I was kinda dancing while playing this one. New players don't die too quickly which gives them a bit of time to figure out how to play.
The negative: I did have a little trouble figuring out the controls. It seemed like they were just a bit over-complicated. I think it might be better to use the left click instead of A and D to hook onto asteroids. I felt like it didn't make sense to have a left hook and a right hook when the spaceship is kinda always facing in one direction. That tended to confuse me. I was never sure which one to click and found myself just mashing the two buttons. I also wasn't able to figure out how to manage my health. It just kept going down. There was a missing objective to the game as well. The endlessness is cool but that becomes monotonous without a high score system and without any objects to collect (correct me if I'm wrong but I didn't come across any kinds of power-ups or anything positive to pick up in the world). I also felt like it was a missed opportunity that I could only move forward or backward but not up or down. I know that would be harder to code but I think it'd be worth it to bring this up to the level of a long-term playable game.
Over all: This is a great concept with great music. The developer definitely has something here. It needs some refining and depth but it held my interest and was enjoyable for a solid 10 minutes. Compared to the few other games in the competition that I've play-tested so far, this one stands out as one of the best.
