- As with anything in this <em>draft</em> statement, this
- is <strong>subject to change without notice</strong>. Why do
- you think they're provided in the game input?
+ You can also override them via game
+ settings <var>roadLength</var> and <var>initialStones</var>,
+ so long as you remember you won't be choosing them for
+ ranking play.

<span>Change Log</span>
</h2>
- <ul>
- <li>
- Fixed the road length fencepost non-issue.
- </li>
- <li>
- Of course that game needed MSG functionality!
- </li>
- <li>
- Enforce the one-stone rule. (that also fixed the legacy
- buh—sorry people! I put an easter egg in exchange)
- </li>
- <li>
- Cutesy defeat animations.
- </li>
- <li>
- Distinct castle sprites!
- </li>
- <li>
- Terminate game when there are no more stones in sight.
- </li>
- <li>
- More pretty. (SRLSLY)
- </li>
- <li>
- No more void maps. (root cause: Java <const>%</const> on a
- negative seed)
- </li>
- </ul>
+ <p>
+ I'm not maintaining the full changelog here anymore as the
+ <a href="https://troll.desast.re/troll.git">game's source
+ repository</a> is now publicly available. I'll just make note
+ of the single latest change, so you can know how far behind you
+ were lagging. Patches welcome, BTW.
+ </p>
+ <p>
+ This draft's last change is:
+ <strong>
+ demo references still existing sprites.
+ </strong>
