is there a cheat in this game?
I was trying some things on Windows desktop. After you save the game at least once, you can go to the Windows registry (regedit dot exe) and in "HKEY_CURRENT_USER\Software\Ferdafs\RickAndMorty" you can change a few things like the money you have or the amount of days that have passed in-game. Then you press Continue in the main menu to use those settings, or Load while playing.
Most of the settings are cryptic, might break the game to change them.
The most useful setting would be the one that gives you all possible items, but it uses some integer value that I have no idea how the game interprets it. EDIT: Actually, it looks like you can only buy two items: the wine bottle and the flute. The purple dildo isn't stored in the inventory. So just setting your money (value named "money_h(...)") to a ridiculous amount like ffff for $65535 ingame money should let you go through the game without much trouble.
