I played around with platformer Brain Box and discovered that there is no jump limit option. So, I added it into code. Add your platforms to "Platform" Collision Group and drag asset into your game world. Download: https://www.hanomaxgames.com/Downloads/platformer_brainBox_jumpLimit.bbasset
Sorry guys, who already downloaded this and tried. Jump counter was in wrong line in code and it didn't work as expected. It is fixed now and link is updated.
I just found out, that Smart Penguins has already made video about that, how to limit jumps, and explains code very well. Also, you can find other good videos on his channel.
Your bbasset is not working in the current version 3.1.2. When you jump and try again the animation of moving bugs and jump bugs too.
