I like the tension you and dread with the glitch you created. A personal issue I did have with the game is the lack of checkpoints. It's pretty frustrating to finally reach the last bug only for the glitch to corner you and you end up starting from the very beginning.
Overall, I love the tension and dread you established which is very relatable from a developer's standpoint. *Shudder* The bugs...
Anyways, hoping to see more levels and even more scary ways to portray bugs and viruses in a game's code. Well done! :)
