Glad you liked the idea! Wall jumping is a feature in the game, I didn't have time to implement a tutorial sadly and resulted to leaving a quick tip on the Game Page. If you jump next to surface, break away from it and then come back to it (and then jumping again), you'll wall jump. I wasn't able to get it feeling right due to lack of time, and thus its slightly difficult to pull off.

Thank you! Glad you enjoyed the concept! About wall jumping off falling blocks, it is actually possible to do so, but I wasn't able to tweak the speed of both the player and blocks in order to make it easier to pull it off.  But i'll definitely try and change that later on.
