 # Tetris written in SDL2 and C++
+
+## TODO
+
+- Game Over screen
+- Add Gamemodes
+  - Gamemode selection screen
+- Save score
+  - Think of a better scoring system
+  - Save to a file
+- Maybe Multiplayer
+  - Select 1 Player/2 Player in the title
+  - Peer2Peer or server based?
+    - Server based could also cloud save the savegame
+- Cleanup code/Refractor
+- Comment/Document stuff
