Added progress bars, win / lose conditions and enemies.
I'm experimenting with using #CSS animations as timing functions for #JS and effects are promising.

When I had designed a chunk of the world I printed it and gave it to my 10 year old son who helped me to work out the position of the rainbows and the doors and keys to try and make it an interesting experience. #gamedesign #js13k

Here's a screenshot of the game and the splash screen. It's almost done now. A bit of level tidying and then some play-testing but I'm pretty happy with it. #js13k #gamedev #indiedev #javascript

DAYS 15-25 #JS13K

~1.5kB remaining. Essential before Sept 12th: fill in placeholder enemy behaviors and sound effects.

All 18 holes of my JS13K golf game are procedurally generated on startup. Squeezing this much variety into 13KB was a real trick! 🏌️⛳ #js13k #gamedev

PRANCE & UPCORN have both been submitted to #js13k… and I kid you not, my brain instantly went:

“Okay, roughly 6 days left… can we make a 3rd? There are some optional challenges…”

Well… I guess here we go again. 🦄

big updates for my little golf game thanks to player feedback! improved swing meter, better physics, tweaked course difficulty. ☀️⛳️ #js13k #gamedev

I'm a little bit late to start work for #js13k submission, but better to start late than never.
Board generation, selecting, matching and replacing orbs are basically finished.
There's still a lot of work to do, but hopefully I'll be able to finish what I have in mind.
