A little message or something after beating the box would have been cool, just to give it a little bit of a conclusion. I found the upgrades a little easy to get to, as well; normally I'm just barely hanging on before I've saved enough for an upgrade, but in this game it seemed like just as new enemies came in, and the difficulty started to climb, I could afford the next gun, and everything was easy again.
All in all though, this was a lot of fun. I played till the end, at least. I'd like to see more stuff like this.
It looks really promising. The custom cursor seems to jump a bit and lag. I would have rated this as a 4-5 but the cursor issue is so bad it's really not fun to play.
Great game. Loved the sound track and game play. Maybe add an ending?
Quite a good game, the health bar has a glitch in it where, even though you get the extra life, the bar doesn't go back up with it (when recovering) and there should be a screen where it says "A winner, is YOU!" or something to that effect.
On a side note: The music is perfect, makes you feel like you're playing an old SNES game.
