What you mean with itch.io jam system? That's my first jam. What problems may I will face? I guess when I finish my game just submit, upload instalation files and wait for... Finally rest. Am I wrong?
And BTW today was a waste of time... All day spend on trying to implement mini game about opening locks and finally I didn't made it and decide to leave this feature for later... Too complex idea to create on short time. As a punish I decide to no sleep tonight to add postprocessing and I guess cry a little bit because that my first time with implementing postprocessing :)
