+#### Todo :construction:
+
+- [ ] Add a way to change the snake speed
+  - [ ] Make a ui to switch the snake speed
+  - [x] Interal implementation of the snake speed
+- [ ] Implement Highscore System
+  - [ ] Make the ui
+  - [ ] Internal Implementation
+
+#### Bugs :bug:
+
+- ~~Snake going through the walls~~
+- ~~Food spawning in the walls~~
+- Remove all the logging in the ui
+- Pausing delayed if esc is pressed but not if p is pressed.
+
+#### Maybe in the future
+
+- [ ] Autoplay the game using a simple pathfinding algorithm (to show on [r/unixporn](https://reddit.com/r/unixporn) of course :clown_face:)
