Generally really cool game. It has nice ideas, a lot of stuff for a 7 day jam and nice visuals and music. I like the tutorial and how much diversity you have in the game.
The time in the tutorial until you get something to do could be shorter though, you have to wait there quite some time, until you can play. Even though the mechanics are very cool and its fun to play I find it really hard to both dodge enemy attack and look into your magazine to know which bullet is coming next and if you have to spin it, which makes a lot of the gameplay much more random than it should be.
However, it was a cool experience and got a lot of content for one week of development. Keep it up! :)
