Awesome, thanks for the video and feedback!
And yes, you're absolutely right about the map size and the fact that's it's a bit too empty at the moment. I added some more rocks, trees and grass last minute but I should have spent a little more time on it then I did :)
PS: for now you can see the high scores for my game and other Ludum Dare games here: https://dollarone.games/elympics/leaderboards.html (this leaderboard was setup for the game jam though, so i'm not sure how long it will stay online)
Also, you can right-click your mouse to fire grenades, I probably should have made that a bit clearer instead of just hiding it in the wall of text in the menu :)
