Godot haxe example

Anyone try to build squash the creeps example ? for me look like not working, i have install mono beforehand ? or build in monodevelop ?

What sort of errors are you getting?
When I have compiling troubles at first try, I will check the Haxe version and library versions. The creeps example was last updated Nov 11, 2021 so you may wish to try Haxe 4.2.5.
I would also recommend using VSCode over MonoDevelop.
That all said, I know nothing about Godot.
