* reflect light rays, dangerous lasers and floating spirit creatures
* explore the halls and dungeons of TRI, collect treasures and solve puzzles

Hello there. A few months ago I completed the 1st version with just a few levels (I don't remember the number) and I see that in the Preorder there are 3 more levels and a notification in the menu that the savegames are broken. I have no problem with that, the game is in development but, I would realy appreciate if someone would share a savegame compatible with the new version that picks up from where the new levels were added.

Then you should be able to choose level 11, which is the first new level in MagicalMonk.

Thanks, it works!

I will anyway replay all the game when it will be in final state but for the time being I just wanted to pick up from where I left. The architecture just looks so surreal and nice that I overuse the F8 to do screenshots :D

Once again, congratulations for the game!

Looks very imaginative. I love surreal games like this.
Kind of salty I missed the 5 dollar sale.
