it looks like you copy pasted someone elses jam page and made a few changes.. please proof read what you are posting on the internet, especially something you expect people to dump time into like a gamejam.

Also im not even sure if you  /can/ download gms1.4 anymore. I think you need GMS2 to be able to download it for legacy reasons, meaning that this jam is very exclusive of people who didnt use GMS1.4 and still have it installed. (Unless it isn't??? The jam page says you dont need to use GMS1.4)
