Boats on Rails Final Presentation

Boats on Rails is a boat-racing game where the player races against enemy AIs and evades obstacles. To these ends, primary gameplay mechanics (besides accelerating and steering) include drifting, and strafing via cannon fire.

The game is designed to be “fast and forgiving” — we want to keep players in the action as much as possible. Achieving this goal required several iterations and playtesting feedback; the exact mechanics of the drifting motion, and the collision physics were continually refined over the course of development. In particular, drifting was changed from a toggle-activated ability to a key-holding paradigm, and was successively modified to be less abrupt and more smooth. The collision physics was continually refined to be less punishing — much more bouncy and elastic than is strictly realistic. Recoil from cannon-fire was made to be stronger to aid in the strafing mechanic, as alpha play-testers found strafing to be more useful than trying to hit things.

After final playtesting, we made some minor tune-ups to the game, including:

  • Re-balancing the AI (to make it easier to recover if you get in last, and harder to stay in first),
  • adding more directional arrows to aid navigation,
  • fixed bugs in the minimap, and
  • made it more clear where the player was on the minimap,
  • reduced the duration of the “spin-out” animation to make it less punishing, and
  • added minor polish effects (like flying woodchips when getting hit with cannon balls).

Note that the video below is “dubbed over” with the background sound track, because it was edited to be below 2 minutes and leaving the original sound in would have been choppy.

Playable game for those interested.
