This game wasn't made by the one who submitted it but me instead and he obviously has no rights to it. This dude has been doing this thing (joining all jams with prices with different stolen games) for years now, this is at least the fourth time he is using one of my projects it seems.

I have reported these to itch too but they seem to be taking their time in reacting to it.

Damn that's horrible..hope it gets all sorted out asap. If you need any sort of help, LittleSmallStudios team is on your side :).

Hello, thanks for your information. In our case, it's impossible to win a jam with a game that you don't own because, as the winner, we will ask to add that game to our platform and integrate our SDK for extra UA tests, so it's impossible to do if you don't have that game's repository
