The graphics, audio and idea are all really well executed. Seriously, the fact that you manged to create this art and think of an idea like this in 48 hours is incredible. The gameplay is, while a bit rough, still really fun.
The dificulty was a bit high, and it was easy to manipulate the system by just repeatedly mashing right click after jumping, diving and shooting. Maybe it could be fixed with a system in which you have to press diferent buttons in a specific time limit or you take damage? I'm not really sure. Also, the frame rate was kinda low, but that's probably because I played it on a laptop.
In conclusion, despite being a bit rough around the edges, the core concept, presentation and gameplay made it really fun!
