Hey, I just played this game. I think you have an interesting puzzle concept that has potential. I don't know which direction you're going to try to take this but in its current state there are a few issues. Mainly the camera controls are jank. Sometimes it takes several inputs to get it moving and sometimes it doesn't. The gameplay is simple and fun, the objective is clear. However, it's not clear when starting the game that each level pack introduces different mechanics. Also, it should be made clear to the player how many levels are in each pack before or while they're playing. I kept wondering how many levels remain in the pack and if you exit you cannot pick up where you left off. Other than that, I think if you polish it and improve the visual aspects this can be an interesting game to play. You have a solid concept here.
