Awesome! It took me awhile to figure out how to destroy the target and cracked blocks, and what all the character abilities were. I would say that you might want to force the player to learn the mechanics and block types one at a time. Maybe you unlock skills by reading a stone tablet or opening a chest with bombs in it to learn that skill. Then the player could go back and get those missed targets with the newly learned skills. To force the player to learn that arrows break targets, you could have a red target block the path forward at the very start, forcing them to figure out to shoot it to keep going. Also, having hit points, killable enemies, and the threat of death could make it more fun.
