Really!!! so far I can't think of any game for the topic

Don't worry! Soon you will find an idea that you want to pursue!

Watch some videos of games you like and see if you can "fill in your hole" to help your creative thought ;)... no not good k I will leave DX

So how i think of ideas is i think of 1 topic and build from that as in i think of ... "Frogs" okay what can a frog do... how about... eat the screen... in holes, and the goal is to clear the whole level in ___ seconds

so you could try that idea aswell... just think of a topic, and then think about it for like 5 minutes, if u get nothing... just think of another topic

What if you were a star that's trying to shine light on an earth-like planet but your light only shines in one direction for some reason, so you use black holes to bend your light to that planet.

Seems like alot of people went with the option of a game centered around black holes, but there's also options like a air balloon or ship that keeps getting holes just keep thinking about it and something will come to you im sure:)

Holes in memory, blackout. Holes in rocks=caves.

When one of our team members gets stumped we get them to take a break, when this happens, they typically come back with a new mind set. Hope this works out for your problem. Good luck with the jam!
