This game suffers from the same thing a lot of the games we've developed so far suffers from: you're not scaling the graphics properly. I've done my best to squint through it all, and the graphics seems to have a level of polish behind that rough coat of blur. The game also lacks any sense of objective, which is necessary for it to be considered a game. The controls are also very floaty, which meant I crashed into enemies constantly, and there was no health that I noticed either.
However negative I may seem, there are some positives.
First, I love the animation of the sprites, it feels natural through and through. Second, the idea of the game does not sound too bad either, with the player going as deep as possible, rather than having a swarm of enemy ships like most other games have. Although this idea couldn't be followed through on, it's a great idea regardless.
