Nice game! Some feature requests:
- Can you add a button for fullscreen?
- Button to reset the level (as opposed to spam undo button)
- Button to mute music/sfx separately
- “Draw” (hold LMB +drag across tiles) to place rail instead of clicking manually, bonus if going horizontal to vertical or vice versa place a curved tile automatically.
- RMB to delete (also with draw)
- MMB to rotate
