Hi Itooh, thanks for playing ! On level 3 we had a flashy portal on the grotto "rocky rectangle" thing, all there is to do is to hit it to go to the next level (its a cavern dungeon thing), however after the last patch + export, the visual marker disappeared (you can still change areas if you find the spot though). It's going to be fixed in the next patch, sorry for the confusion. (My sister and her husband had the same problem and they searched for like 15 minutes!) Thanks for the compliments, we aim to make the game much better and re-release a more complete version soon.
