To improve security, we will soon start forcing password resets for any account that uses a weak password on the next login. If you have a weak password or a defunct email, please update it now to prevent future disruption.
If you wanna cheat to the end, its in the regestry. You'll need to make a save file first so play to the end of the first level. (I would post a save file but its easier to just do it yourself)
Open Regestry Editor -> HKEY_CURRENT_USER\SOFTWARE\com.loolust\69IrisHot -> slot0_xxxxxxx ->
Change the part that says "Progress=1" to "Progress=18" and you should be at the end of the game.
