The game is really soothing, and I really like the vibe ^^. It reminds me of games like A Little to the Left.
I do have a few minor criticisms, of course. For example, the to-do list should be in order, at least for the tutorial. Additionally, there should be the ability to add or change elements in the manual.
I also encountered a major bug that crashed my game. When I removed the cover where the battery was, dismantled everything, and then put it back, I was able to place the new battery on top of the old one. When I pressed R, it just crashed. Maybe there should be a visual effect when you have the old battery.
On the Game Joy, I was able to stack two chips on top of each other as well.
It's a shame about all these crashes because the game is really good, and I would have liked to see more of it. But overall, it's really well done.
