You’re welcome. Maybe you don’t have to make all 20, but I think the idea is just to get your feet wet with game development with simple stuff first (baby steps), rather than diving into the deep end of the pool without knowing how to swim. Maybe you’ll feel you have the hang of it after making a handful of them.
Ah, yes, I forgot about game jams! They sound like they would really help you spend some concentrated time on game dev and design and progress quickly. Thanks.
