I tried the demo. I like the look of this game, and the unique gameplay. I was a little confused by the artwork, it was kind of hard to tell what parts of the level were walls, and what you could pass over. That would be my biggest concern at this point, readability. I think it should be really clear what you can pass through and what will stop you.
Thanks a lot for taking the time to play my demo and even more thanks for giving me feedback.
Yes you are correct in that it is not clear enough to see where you can go through or not at times. I am going to backtrack to the art and try and make it more clear. I have a new demo coming out in a few weeks so no promises but I will try to get that fixed for the new demo.
