Short but oh so sweet ! The puzzle design in this one is really well done. Tutorial and unlocking new capabilities was also very nice, more games should take this as an example ! Also maximum points for theme !
There were a few rough patches where the game froze for a split second (first time destroying a box for example).
Besides that the only critisism I have is that it's very hard to know where the projctile will bounce to when colliding with a magnet block.
Great job altogether !
