Hi, I've notice in other game jams that some people submits their game for free but enabled the option to accept donations so people who played and enjoyed could leave a tip if they wanted

Since I didn't read anything about this on the rules I was wondering:

Is it ok to have the "receive a donation" option in the game submitted to this jam or is it not allowed? 

I'm afraid of disqualifying my game by accident if I submit a project that accepts donations... 

Not that I believe that people would donate considering the symplicity of my game, but if anyone did like it and decided to give me a tip (like I saw happening to other people) it would mean a lot to me and help me a ton too

But I'm extremely afraid and would never want break the rules so I thought it would be better to ask first

Thanks in advance!
