Solid game! I thought it was pretty fun, but I have two big criticisms with jumping. First, the base height is too low to really jump once over any of the enemies, you have to fly. The second thing is that I think that the amount of time you're allowed to fly for and how the stamina bar just resets automatically is a little bit to OP. It would probably be good if you lower the amount of time you can fly, and then give it some extra time before resetting it (perhaps it fills in slowly?). But overall, it was very enjoyable, so good job!
