As others have said, love the game, think the hit boxes could use some tweaking, but if you really fine tuned those platforming controls you would have an instant hit on your hands (in my opinion)

Love the concept and the artwork is clean. I found the hitboxes around the spikes are perhaps a little too large? Or perhaps I need to improve hehe. Great job :)

I thought this concept was a really great way to get both fun gameplay and fit perfectly with the black and white theme. 

The hit boxes for some of the obstacles are kind of off though. It reminded me of the neopets game Escape from Meridell Castle if you've heard of it. 

Maybe if, for example, the spikes had a different look, to better show the hitbox is actually a square.
