Unfortunately, the mod is unintentionally broken and unplayable past an Early Main Quest. It's at a Golden Tower, you have to beat 2 zombies that resurrect infinitely... And yes I can't progress until you beat the fight. I checked online, and the paid game released a hot fix. This mod is based on the broken unplayable version of the game :/
I didn't see anybody on the comments even mention it, but it's broken for all phone types .. the game itself is broken.
Please update if you see fit, thanks for the work regardless!
