The Boss Is pretty awesome but is very difficult to kill it, and i can't move the camera on y-axis but overall great game Brother :)

I'm glad you liked the boss.
You can play all three of the bosses individually by going to different doors, not sure which one you tried (the horned boss is very hard LOL). And you can use the "Game Jam Cheat" in the pause menu to crank up your stats to make it easier :) And yes, the y-axis is locked by design when you are locked-on to the target. If you un-target (by pressing the same button again) then you can move the camera in the y axis.
Thanks for playing! And good luck!
