Very well designed game!
The art, sounds and mechanics fit together perfectly. Congratulations on working out so many details! The tutorial video is fun, the mini games work well. And I see you had time to write a diary in the development log.
It took me quite a while to figure out what exactly the main goal was, but in the end I managed to complete the game by just focusing on entering directions and fixing the engine.
For some reason, the steam and smoke effects require too much performance for me. If they are not visible on the screen, the game runs at normal fps, otherwise it drops to 4 fps. (However, my device may be too weak.)
Overall, this is an impressive game!
