bug

the shield upgrade has a bad habit of detaching off of your ship and spinning beside you or even get stuck to the side of the screen. also the 360 degree turning would give people a different way of play. and last, the ship shouldn't go to the other side when you go off the screen like some infinite loop, makes the game too easy. hold left (or right) + Z + continuously press X = you cant lose. other than that its a pretty solid game. folks remember this is just a demo, not the full game. He probably posted the demo to get feedback

glitch

second level, about halfway through the level i destroyed a green block and the screen just stayed white and froze.

Concept isn't bad, once I got used to the controls it was a bit easier.. and set it up so you can turn the ship 360.

Garbage

I've seen better things stuck to the hairs on my ass then what you've shown me here. If you're going to use game making software so you don't have to code your own crap, at least do it with some effort.
