# 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

above run with `perf stat bin/paradiso_pong` shows some really bad performance issues.
