Hi Chelowo! Thank you for playing Emerald Wasp, I'm glad you're liking the game so far >\\\<
It seems you got locked into the bad endings, the path for the endings is divided mid-game: you'd have to load a safe file back to the gem chasing quest without having Archie inspect every bed and poke the skull in the skeleton room (and if you did the Hideout, don't tell him you like pineapple on pizza xD)
If you overwrote the savefiles and don't have a backup I can look for one of mine and send it to you! Let me know!
