Unlocking that game is a great idea!
Maybe you'll want to remove a forest from the manual, since there's no information about it anyway. Just leaving it in the credits section is a nice obscure reference to it.
Normally I would say you use exportglobals and importglobals to save state, but in this case you could load and save the game instead. But then you would need to use both a newgame and loadgame script.
Oh, I completely forgot to point out a few other things.
James Paige is misspelt as "James Page" in two places in the manual. Newbie also copied over that same typo to the
Owlbears description. (BTW, I don't care, but if you want a fairly complete credits list for the engine, I suggested "James & Ralph are the developers of the OHRRPGCE along with Mike, Simon, Jay, Yuriy and yet more contributors" for Surlaw's game.)
Also, "MorpheusKitami" is inconsistently written as "Morpheus Kitami" all over the place, seems a bit sloppy.
So I just tried out the new Owlbears. It seems that the flight paths of the gremlins has changed. Is this intentional, or just result of the faster scaling? It seems a bit like a bug. Now the grelims generally fly around the screen about once almost entirely off the border of the screen, just appearing at one or two corners if at all, and being impossible to hit at this early stage. I can't even tell how many times they circle before diving (although I realise this is random), since you can't see how many grelims have spawned or where they are.
Here's an easy target, the score for my first game: 65,900.
BTW, if the only scripts you're using from the 3rd party HSI are the trig functions, I wrote those and I don't care about attribution; they're going to be built into the engine at some point anyway. Even the whole package doesn't ask for attribution.
