Todo

Here some ideas for improving this tiny engine:

Rendering

  • replace the OpenGL renderer with a Vulkan backend
  • add animatable sprites (access to UV mapping and tiling)
  • add a SDF based renderer (parametric tiles and font rendering)

Game Support

  • audio!
  • some minimal animation system with tweening with different f-curves

System Level

  • add a Asset handler to load cache and manage assets
  • introspection of file system if we load assset

Design

  • replace some of the 'unkown source' assets

Build / Dev Support

  • add a test rig either with Snitch or Catch2
  • write some reasonable testcases
  • add CPU and GPU benchmarks to address various issues
