The game would be good if it weren't for a few fatal problems:
- Trying to jump up and into a space the same size as the character is extremely difficult for some reason; the character just won't go into the space sometimes. While this would be annoying in a normal platformer, it makes the game even more difficult since when you fail to make the jump, the other mirror image of the character has moved out of place, forcing the player to either realign the other character to the proper spot it needs to be in or to restart the level because the level is now unwinnable.
- The wall jumping also doesn't always work for some reason.
- The controls should be explained in the game or in the description (having the controls explained in both would be preferable). While the controls and mechanic might seem intuitive to you, every game has different rules.
- I'd suggest making the R button the restart button for the level. In a game like this, restarting might be done multiple times for some players so having to go to a menu to do it is both annoying and a waste of time.
I like the aesthetics of the game as well as the gameplay, but the problems make the undesirable to play unless they get fixed.
