yeah, I thing there is still some work needed here :)
having two guns is a nice vision, but a lot of minor things are bugging (getting hung up on ledges, screen transition, esp. to the left, etc)
and teaching new mechanics while being in the middle of a jump after a screen transition ist just pure evil. there wasn't even a way up again, right? so I had to restart the game. In the end I managed to get to the boss by sliding around in the pit offscreen …
PS: why does the blue bullet have 'bullet drop', and the red one doesn't?

Indeed the game's physics (sudden move, collisions) are quite buggy and makes the game hard to play, the concept is quite simple and tutorials ruins the experience.

Like the feel of it but for me whenever I fell off the bottom it didn't respawn me and basically softlocked the game?

I like this, I also think that idea is quite fun, nice!

The idea is cool! Keep it up!

could use  more polish, but good job regardless

Really awesome concept! well done :)
