The game was quite fun except for that it opened a new window, giving a bunch of error. A full screen version would do good, and if you keep pressing the mouse button projectiles don't stop shooting. Also try increasing the speed. Other than that the game is fun to play.

Fun game overall! I enjoyed the variety of stages you had and the enemy path finding seemed to work great (that's something I always struggle with). The particle fx was really nice, especially when bullets impacted the walls.

If you wanted to improve some, I suggest upping the difficulty some. I never really felt threatened by the enemies in the game, I could either breeze past them or destroy them quickly enough to not have any issues. A simple difficulty option that increases damage from enemies and player damage would be a simple fix that could add a lot of replay value.

Overall, quality and fun game!

I think if this had've been a shipping build instead of a debug build (lots of errors in the console, in the background as I was playing), it had a few more enemy types, and the campaign mode was a bit faster, it would've been great. As it was, it was a solid game, good base, but it kind of lacked a few things.
