Great game! Excellent at the start, but the quality fades away as a player proceeds trough the game. There are some game-breaking bugs and "cheating" tips, that are still bugs.
Whenever I go in the locket I can't get out.
Sometimes I can run into the wall and slowing my walk speed I can walk trough them.
It's kinda weak that you can only win the level by killing the red enemy.
Some tutorial would be nice, as well as reminding players that they can move with arrow keys THAT DON'T MAKE SOUND WAVES!
The idea is great, but the game needs some tips, better tutorial, bug fixes and maybe some voice acting because, you know, you are blind and you should not be able to read, but this is good enough.
One more thing: Add some slow and some fast music for battle/non-battle moments. Even very quiet, it would be good.
