Hey, I just wanted to ask if I can make 2d game because I'm not that good at 3d.
I read the rules but it didn't mention about 3d or 2d.
Yes you can use 2D but you need to make it appear to look 3D. I did that with my jam game in 2022. I used Love2D to draw images/sprites (from back to front) so that you get a faux 3D view.
The method used can be referred to as the "Painter's Algorithm".
