I developed LDtk as the backbone of my game dev life.
My first game, Nuclear Blaze, relies entirely on this tool, and was even intended as a “proof-of-concept” for it.
I tried to make it my dream tool, while keeping the scope reasonable. This means that LDtk sure has many features, but not all of them.
It is designed with user experience first in mind: do less, but do it right.
