Hi, thanks for playing! I'm glad you enjoyed it.
1) Thanks for reporting the error, I missed this place, cliff should be higher there. I realize that there are more such places, some I could overlook when testing, the rest result from the necessity to limit the map. I think it is better to insert a stone wall than to make the fade out and the text "I have to turn around". In the next major update I will try to reduce the artificiality of barriers.
2) Save options are a bigger task, so I omitted it in the current version, but they are on my to do list. The current version of the game can be completed in less than 10 minutes, if you know where all the orbs and secrets are located.
Thanks for feedback!
