I concur, adding an upgrade system would make this infinitely more fun!

Nice graphics. Voxels are cool. It was difficult for me, but I am someone who likes easy games.

The art is great, and the idea is phenomenal, but it's a bit much. A health bar or some indicator of health would be nice, and I think it'd be interesting to include some sort of upgrade system so it can keep starting off insanely difficult, but it would have to take you a few rounds to truly get anywhere. Overall an interesting and fun little game.

Too hard. The angle is something uncommon, but makes it very hard at the beginning to get used to the ship speed, distance, where to aim to doge bullets ... compared to that there are too many enemies at the beginning.

Also: really? Push the spacebar for every single shot? Couldn't you just make it enough to hold the spacebar?
