I though this was a nice idea until the pause mechanic came in. That's when I though this was great! This game has a lot of potential for interesting puzzles. Just a bit sad that the most interesting mechanic ended up getting introduced in the last level, left me wanting more :D I also agree with some of the others that while limiting the player to one mechanic at a time is a cool concept, scrolling through the options can be a bit tedious. I still enjoyed working through puzzles a lot, so well done!
