wedge: a puzzle game
====================
![screenshot](screenshot.jpg?raw=true)
Mechanics:
- **Objective:** Get the two players to reach the goals by navigating the level and pushing blocks around.
- Blocks with triangular sections will push other blocks in the other direction.
- Blocks of the same color will always move together.
Controls: WASD for the left player and IJKL for the right player
To-do list
----------
- [ ] Gameplay
- [x] Collision algorithm
- [x] Primitive animations
- [ ] Orientation indicator
- [ ] Unique textures
- [ ] Cosmetics
- [ ] A real menu interface
- [ ] In-game editor
Credits
