Hey, the program seems alot interesting, but, there isnt zoom in/out yet??
Thank you for your feedback! Unfortunately there is no zoom. I am planning to completely redesign this editor and improve it in the future. Unfortunately I have no time no resources to do this quickly.
One solution for now is to scale the tileset in some graphics program, and use it instead. Later you can use the original tileset and it will be compatible with the level.
