This is my second attempt!
I will probably use WebGL and prepare some simple 2D-tile engine that can read Tiled (map editor) output. I also plan to use Graphics Gale but I might decide to stick with Gimp.
Some other stuff that I’ll use:
* OpenMPT or Musagi
* A simple starting utility library for vector math, simple geometry etc. (same as for LD22 but with some additions for WebGL stuff that I’ll post a link to later)
