Wow! Really smooth pixel-shooter. I loved it. Some small points of feedback:
- You can only go back to campaign selection by pressing Esc, which makes the game exit fullscreen
- Automatically starting the next level would be really nice, going back to the menu every time breaks the pace a bit
- From the comments I understand that you have to play an entire campaign without taking damage to unlock the golden weapons? But this is not explained anywhere in the game
The soundtrack and audio design are awesome. There is some interesting movement tech in there when combining gun knockback for high jumps and the dash for extra sideways speed.
Overall very Polish-ed game that is up there in quality.
EDIT: a small bug I found, when I used the portal gun and walked into the portal it sent me to the tutorial level for some reason
