ahaha i worry the same thing about my own devlog. i am a rambly person in general, i guess. i think that if you're excited about what you're doing, and your excitement shows in your writing, then your devlog will be fun to read regardless of length. :>
I also am a rambly person haha, for sure. Thank you for your kind words! Honestly I am so excited about game dev in general I'm glad I finally have a place to scream about it lol.
