Yeah... the walking speed is definitely being a matter of discussion. Walking slowly is great for aiming your dash precisely, but bad por walking past enemies and moving overall. Walking fast would be the opposite, and we also didn't want to allow people to avoid the rock's crush attack without dashing.
I'm glad you liked the concept and the core mechanic :D. It's a bit different than usual to land hits, you have to dash through the enemy (start on one side, hit him, finish your dash on the other side).
