It has been said, but it is difficult to know where the cover spots are. Your game is actually pretty similar to ours, and one of the critiques we got is being able to switch between our weapon options. Which is what your game did. So good job on that, switching between your weapons is definitely the smarter choice. I do think the game is a bit difficult, but if you expanded the map a bit or had fewer obstacles I think that'd make it easier and a bit more fun. Good job for only having 4 days, seriously impressive to get this done within that timeframe!
