I also just submitted mine over! Had so many ideas but had to sacrifice a lot of them due to the time constraints and me having work on Friday. But I'm glad to have been able to submit it in!
Viewing post in JUST SUBMITTED MY GAME!!! AAAAAHHH
RPG Maker MV (and most likely it’s successor RPG Maker MZ) supports web browser play! I used MV for my submission if you want to go check it out! You might have to go full screen on my game though because for some reason itch.io didn't format the frame size properly to RPG Maker's default game window size.
My game is called "I Cannot Remove This Monkey Suit!"
