So my problem is that when I hold the left arrow key and up arrow key, I can't jump. At all. Yet when I hold the right arrow key and up key I can just perfectly fine. This is driving me insane, trying to jump onto walls and such. Has anyone had this issue, and is there anyway to fix it?

Trying to quit cigarettes and playing hard levels with this damn jumping thing is very difficult 

This level is my first knytt level. A while back on my now perished computer I had another level that I made, but it got lost when I chucked my computer in the trash. This level is not finished, not near finished, and when I finish it is very much unknown to me. Some days I spend hours on it, some times its days before I even think about it.

So. Storyline? Um, you're a knytt who is exploring the world. So creative, I know.

The environment changes frequently with little warning, so if you don't like that then this level is not for you. It is going to be big. Right now it's probably a good sized medium, but it's going to be large. There are MANY secrets, secret rooms, secret areas, secret worlds. If you go straight through it without looking you will miss about 80% of the level and will not be able to win. So.
There are some challenges, nothing above hard, and most of them aren't even that. It's not meant to be a challenge level.  
Also there a lot of different areas in this world, different lands too. Some are crucial to winning and some aren't. I haven't decided for sure if I'm making multiple endings, but I think I'm going to, maybe.
I'm hoping this will be a level where you can play many times and still find new areas/places/things.  

I love it to death and it's so much fun. But please, I welcome any and all criticism and I need some beta testers because I'm sure to miss something if I look over it by myself.  


IMPORTANT NOTE:
I did not make ANY of the tilesets or backgrounds.
When I release this level I will credit all the creators.

I'm working on a level, my first actually. But if I used tilesets from other peoples levels(custom ones), gave them credit, but didn't ask them, is that ok?
