So strange, it has been working well on all my computers I've tested on. I just added one more fix in v1.4/v1.5/v1.6/v1.7(been fixing a few things!, haha) that may help with the unwieldy jumping.
Also, as far as not being able to jump again, there is a stamina bar and that should refill after a second or so on the ground.... but if it wasn't refilling then the fix I just put in may also fix that issue for you too.

Hey, I'm really sorry, but it's just not working for me... I don't know why. I'm on a Microsoft Surface Book 2 running Windows 10. I can only jump off of the platform once, but I immediately fall to the ground. The stamina bar is at full power, but I can't jump. Pushing the A key now moves the bee to the left. Space bar and right-click do nothing. I still have no problem with the shooting feature. Anyway, I think I have at least seen some of your game potential (the trailer is genius) and can tell you put a ton of effort into it. Hopefully, one day I'll be able to play it! :)
