Hey, a fellow developer making a retro-themed computer game for the jam! I like your BIOS and startup sequence much more than what I've tried to do in some of my games, and you did a great job at convincingly using effects, sound and visuals to convey the idea of a bug in an old computer. There's some nice little coding references in there too, like how health is represented as a set of commands to delete the player to the bin. I did not expect whatsoever I'd be playing a shoot-em-up from the outset, and it's a nice surprise that handles well. There's some decent quality of life design choices here like guiding the player and tooltips. You honestly could easily make this into a full experience and flesh out the environment in creative ways as the physical and digital spaces you could imagine inside computer infrastructure - like how you've done with the creative ASCII in the kernel security boss. Hmm - for feedback, the only thing is thinking about the grid based movement, which is true to the design of a retro game, but also atypical for a shoot-em-up which usually demands freedom of movement to make the player feel like they can fairly avoid bullets that don't follow the grid. But it's a very valid aesthetic choice. Congrats on getting this out in so short a time, and it really is something I hope you can build on - or something similar!
