surprisingly, not bad!
The art is the highlight, but because the game is small and a lot of new mechanics are introduced gameplay managed to be fun too!
Hello, sorry for the long time reply. Thanks for the good review!
No, all the coins can be picked up:
the first in the large room after "the head"
the second in the store to the right of the room
the third in the hidden passage to the left of the corridor to the toxic room
the last 2 coins are in the toxic room
