This game was a fun concept. Defeat your darkest inner thoughts! I liked the Zelda homage, and the first level's game design was really well put together to guide me where you wanted me. The sound effects were fun.
On the second level I went the wrong way(left) and got stuck in a situation where I couldn't progress because enemies were in an inaccessible area.
Based on the overall difficulty of the game, I would recommend one or two of a few things-
-Increase the range of the player attack
-Make every enemy drop a heart
-Allow wall jumping to fully ascend you up to the top
-Add more helper mechanics to help the player do what they are intending to do.
I made it to the end, but the big baddie bugged out at the top. Fairly complete game, though :D
