This is quite nice for a first game, congrats on making it! I love the vibes of it and I enjoyed the main mechanic and figuring out how to get through the levels. It was pretty easy, but a lot of the time in Game Jam games, its easier to make a hard game than an easy one, but you struck a perfect balance here.

To dive in deeper, I was surprised that running and interacting with mechanics at all - you only ever interact with the door, and theres never a reason not to run, so it left my fingers pretty cramped. I also found the scrolling with the mouse to be pretty janky. In some areas, like the first one, its super sensitive and the deadzone for moving it seems to be pretty small in the center, so combined that with the  scrolling, I got some dizzying moments playing through the game. Luckily it was short, but if it was any longer I wouldnt have been able to play more unfortunately. Some rooms dont have that issue though, so I'm not sure whats up.

Overall though, its a great start for a fun puzzle game. It reminds me of something like Mario vs Donkey Kong on the DS, where you solve puzzles by moving objects around. I think if you focused more on those puzzles, the game would be better off, but considering the month long time frame, you'd probably lose a lot of the art style too. But hey, now that you got a good base of a game, it'd be cool to expand upon it more.
