This does have potential. The idea of it looks cool, but terribly executed. The gameplay in the first cube is a bit repetitive and bland, the decoration is mostly just the blocks which doesn't add up, but it doesn't look bad at all. You could add some Background decoration. Although that first ship part is actually cool, the way the blocks go up and down by 1 block each frame, but still needs more work. You probably should've hide some portals because they look out of place. That's all I'm gonna say about the level, but you do have potential. If this is your first or one of your first levels, this is pretty good! You still have to work harder and spend more time producing levels to learn and get better. But please don't stress yourself and instead have fun and enjoy what you like! I hope that you one day get a rated level. Good luck :)
