what's different between IQ and IQ+ for what's released so far? like, what new is added to the first two towns?
More than I thought, to be honest. He has reworked the prologue, added to the defeat CGs to most of the Pramouton girls, expanded the beach area significantly, added more scenes to the "mistresses", and added voiceovers to boot. Plus, this is the version that will be updated and finished in the future, and that means it's the version that will be ultimately finished.
it use for version 1.0 but in november right? I use the version 1.0 but in last moth and it have some error
No, you have version 1.0, which will not work with the most recent translation we did. As for your error, I would assume it is due to a missing file in your audio folder, either a corrupted file or just a bad download. Maybe something to do with unzipping a file in the wrong system locale too. Actually looking closer, it looks like a machine translation, which I can tell you that the ones I have seen floating around were not well done, and have several translations of callback files that will break the game if altered. My guess is you have one of those MTLs, causing your error.
Eminba, I won't share my own 1.0+ copy, since I am already translating the game without permission, but I am willing to share it with people who are willing to help translate....That being said, perhaps someone else will choose to upload the game itself. It's only about $5 USD on CI-EN though, and worth it imo.
