Challenging and interesting puzzles, but the controls and their wonkiness make me scream bloody murder. Half the time during tricky timing sequences it will decide to lock up running right for instance, or not react to keypresses for half a second. Not to mention that way too many puzzles are conveniently placed right next to the screen edge, so you will run outside and reset the layout.
I initially gave it 4 for the nice art and dialogue, but I had to lower it to 3 because the controls are AWFUL. Half the time I lose an item because it takes 5 clicks before I can move another one already on the grid aside, and then it will fail to register the placement of the new one 50% of the time anyway. That really needs to be fixed.
This is such a little gem. Frustratingly hard, but not enough to make you give up, with a great atmosphere, and an absolutely brilliant soundtrack which would be worth 5 stars alone. Best of all, you can have the OST for cheap, though you really should pay more than the minimal 1$ if you can afford it.
