So first of all, its a good game, fun mechanic and boss battles, I really enjoy the take-a-breath side map. The sprites are not too many but you really utilize them well.
However, there are still so many things to improve. Like the map design, it feels the same every level. The overloaded info, which people have said in the comments. The UI navigation thing, it confused me very much lol.
Overall, I gotta say its insane that you pull off a game like this in just 5 days, it has so many features like the beach map, the comuter UI, the "enter command to recover tape", and all basic dungeon and guns mechanic. Everything feels so polished too. All my respect to you
Btw, love the robot with the animated face, hes so cute
