First of all, thank you so much for all the amazing feedback. You have some really good points that I think I can and will tackle to improve in the update I'm currently working on.
I also wanna say a few things to your complaints.
The air control. I know the air control is a little tight and that is very deliberate. I wouldn't wanna change it too much since I already did all the level design with this amount of it in mind, but I will try my best to make it a little more freeing if I can.
With the main shift mechanic I think you got an amazing point there. I will see how I would implement that though. But I'm sure I can figure it out.
About the idea of having the player go IN the direction instead of the opposite I'm not so sure. This is absolutely an personal preference thing and I think if I change it I would probably alienate some other people, having a setting for this may be a solution.
And lastly: the art problem. YES ... I KNOW. It is very empty. I was scrambling at the last minute to get at least 'some' art done. And I only managed to do the crappy little skyline backgrounds. I'm sorry. I will do better next time.
And the jump you mentioned is just a bit tight. To make it easier you can let go of shift when you initiate a shift jet. This gives you a little speed boost and makes the jump a lot less tricky.
Thanks again for all the feedback and playing the game. And also sorry for my bad grammar ? It's very late for me and I'm tired so if I messed something up ... oops.
