I cannot go to the witch tower north of Oasis (after the talk with the witch, the game freezes, and I need to restart it.) And where is Lonely Cactus to find the bandits? Thanks!
Would you be able to tell me what specific dialogue was said right before the game froze? I'm trying to find why it would freeze at the witch tower but any further details would help. Thanks!
As for the lonely cactus for the bandit clan quest, search the central desert for a screen with only one cactus. If you head to the top-right/northeast of the desert, where there's a cave entrance, the lonely cactus is one screen to the left.
I'm assuming you're talking about the boss at the end of the snake clan cave? If so the treasure in the last room is decorative, you can't take it because it's stolen from other people. The characters should've suggested you go back to Oasis to report it, after which you'll get a reward. I'll consider making this clearer in future versions.
I found the bug and reproduced it, then tested a fix which resolved the issue. All platforms of the game have been upgraded to version 0.9.1 with this new fix in place. You should be able to download the appropriate files then simply move your saves into the new folder and continue playing. If that doesn't resolve the issue let me know. And thank you for finding this bug!
