Fun game and good implementation of the unstable mechanic. I like that you clearly let the player know what the the glitch and for how long the glitch effect will last. Adding more sound effects and vfx especially on power ups and on hitting like a bit of camera shake will enhance the fun :) Good job! 

This is fun! Failing power-ups is my favourite implementation of the theme in the game because it was the most unexpected one after knowing what I would be into. The 2 tunes and the sound effects are catchy and the game looks clean. It controls perfectly, it feels good and the bullet types from the boss were cool. The only thing I missed was some sound effect on hitting and destroying enemies.

Cool!

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 ^^
