Just this page itself looked so awesome I just had to try the game :D
I played the browser version briefly, but I had a really hard time telling between background elements and elements I could walk or wall jump on. Also, sometimes stuff seemed to randomly kill me even when I had time left.
However, I like the pixel art, the animation, and game's level of polish. But I think core mechanics like the visibility of the level should be of higher priority. (I learned this the hard way while making my jam entry.)
Keep up the good work!
