Congrats on your first submission! Most people don't submit unfinished work. You did and it made you officially part of the jam's history! (in a good way of course)
I'm guessing this is also one of your first games (or even your first game). In that case: Well done! The game is pretty rough, let's be honest, but you made your way through developing and publishing a game, which in and of itself is pretty rad. Congrats on sticking through!
The best part about the game are the controls I think. They were a bit hard to learn but once you get the hang of them they feel surprisingly smooth. You also have a tutorial screen, which is nice as well.
The game was lacking a clear objective though and I had a hard time finding out what I actually have to do (and from where I was getting shot). If the different mechanics were communicated a better by the game (i.e. seeing where the shots are coming from, having clear drop off points for supplies, etc.). The idea could actually work as a cool little game.
Honestly, for opting to go 3D on your first submission, you did a good job and you can be proud of your work! If you are new to gamedev I really recommend going 2D next time, as it is a lot simpler to get right.
edit: Oh and by the way - your Linux build is broken. If I start the game it complains about a missing ,pck file (which is the file the actual game content is stored in). Judging by the file size also, this seems to be the case. Your windows build worked flawlessly on Linux using WINE though .
