I'm glad you were able to figure out a way to complete the game, myosotis.
One more thing you may want to do, if you're feeling so inclined ~ and it might possibly help out the devs and/or other players ~ would be to send a detailed description of what you had to go through to complete the game over to the support staff (email @ bottom of the
About tab at top of the page you're looking at).
Please provide as much detail about which device(s) you used, the Android OS version(s) you used, and anything else that may help the coders to understand the extent of the "puzzle closes as soon as I try to access the inventory" problem you experienced.
Thanks!
