It is a comfortable looking game visually. The suit mechanic is genuinely fun and I would like to see more interesting and creative uses for it added in the later areas of the game because it is pretty solid conceptually.
I am terrible with keyboard controls so my review of the demo can't be as indepth and rewarding as the others but if you could possibly see about maybe adding controller support in the next iteration it might go a long way to increasing your testing pool. I did encounter a charging jump glitch but no enemies were involved. I was holding down the charge key and released it the exact moment the 'overload' animation and sound started. What followed is I was unable to move or jump from my current spot. I had to change into chip to gain movement control back but even then the 'overload' sound effect was still playing until I suited up again and did a proper jump.
Thank you for sharing your demo! I hope you keep working on it!
