Hello Pac-Lander, I do have some assets on the GDevelop store which I had to do a good amount of work to get it working, but it's only available on their market.
It's not like it doesn't work, but the tilesets are a complete spritesheet which will need to be separated into sprites for GDevelop.
I've not used Construct3, but if it accepts PNG sprite sheets, it works.
