Really like the concept and fits the theme very well!

Mechanics are also pretty fun, fleshed out, and innovative!
Keeping the gameplay dynamic is also a big plus for me, being able to place player commands and objects anywhere.

Ways to improve:

• Have a tutorial and keyboard input clarified
• Make the way you swap between commands/objects more seamless
• Character gets stuck in mid-air surfaces
• Maybe make walls that the character move into also reverse movement (Not keep running into a wall)
• Make a restart key
• Make levels more dynamic/open so the player can find more ways to solve the level in different ways
  (To accommodate, give the player more commands and objects to experiment within each level)

Otherwise really great game, keep up the good work! :D
