Fun little sidescrolling shooter.
The random negative effects on the powerups is a good use of the theme, and i like the fact that you indicated what happened in the hud as well as having a timer on how long does it last to help avoid confusion.
2 small issues, while i like the limited palette you’ve gone for, i think the brown of the text is a bit to dark and doesn’t contrast well enough against the background color this can make things a bit hard to read, and the multishot powerup increases the volume of the shot sfx quite bit so it would be nice to change this.
Other than that it’s solid fun to play and the controls respond accordingly.
Good job ^^
