First of all: you should use zip files instead of installers in game jams. The game fits the theme and I like the explosion effect (a little bit more screenshake wouldn't have been bad). I like that you tried to make different maps, but in game jams it is usually better to focus on one map and make that one perfect. The voice in the beginning of every round is really annoying. What also annoyed me is the spelling. I know that English is a hard language but just looking in a dictionary if you spelled a word right isn't much work and would already help a lot. An ok game overall.
