What if there was a file size limitation, or making your games 4:3?

Could be cool for a future jam but it's too late to change now. Like by all means go for it if you want.

I know it's too late now, just thought it could be cool!

If you want a ratio limitation, there's already one since the 240×135 resolution is required, so your game must fit a 16/9 ratio. If you'd like a file size limitation, there's the annual js13k jam where you have to create a JS game in 13 Kb or less: https://js13kgames.com/

The reason I didn't do a filesize limitation is because we want lots of people to be able to participate, and with everything using different libraries the challenge would be very uneven (and some would not be able to join)

That's true! Thanks for replying!
