I can’t stop adding features and it’s not good, I need to submit 1.15 today.
Cacti grow in the desert (only on sand, and where temperature is very high and humidity very low). They cause injury when touched. You can plant them, and they will slowly grow to their largest size of 3, provided that there is a lot of sunlight. They hate shade.
Setting cacti on fire is quite destructive because as soon as one block goes up in smoke, all blocks above it go as well.
I also tweaked creatures AI to better avoid dangerous terrain, including cacti of course. Creatures should no longer walk into magma, fire and other painful stuff. Or at least it should happen less often.
Really hope I can get my act together today, stop messing around with minor stuff and submit.
But they looked so cute and prickly, I could not resist finishing them once I saw how they look :-)
