Although there were minor issues with screen formatting, i thought this a pretty unique and interesting concept with intriguing puzzle design
a few things i wished the game had are: when dying, placements aren't undone (so if you are only a little off from finishing a level, like rotating a blower slightly left, then u don't have to set it all up again and again), clearer explanation of what terrains do what and what items do what (i wasn't sure what the torch did until way later on in the game), visual explanation connecting the target button thing to unlocking the door
