Switching weapons constantly is really fun! But goddammit your game is so freaking difficult... To be fair I had a lot of fun. I think the enemies have too much health, it would be more satisfying if they would get destroyed in one hit knowing their spawn rate. 

Nice submission! I agree with Scorched Torch in that the guns feel really balanced. The zero gravity power up did feel a little sluggish though, and I think having a control for lowering myself would be a neat addition.  Also the number of wizards that spawn straight off the bat was slightly overwhelming especially as some guns like the shot gun require you to close the distance to secure a hit. I also think adding more places/object to use as shelter would benefit the game too. Also, I wasn't too sure how to swap the gun for health, but I think that's a me problem lol. Great game! I had a lot of fun bouncing around and shooting to my heart's content. 

The guns feel quite balanced and I never felt like getting any roll was unlucky, though the enemies do seem a bit tough with a large pool of health.
