Hello!
I really appreciate what you did! The game is awesome, I like the music, and the gameplay is highly rewarding (and innovative, too!).
But a nasty bug (I guess it's a bug) is preventing me from progressing: You see, on the 2nd and 3rd Level, after completing stage 2 about halfway thru, I get stuck. I cannot build any more buildings, nor can I revert my move. In addition, the Menu buttons "Return to Menu" and "Exit" (or was it quit? whatever) no longer work. They make the clicking-animation, but nothing happens. I can still change volume or return to the current game.
It only happens after a while, I'm not sure exactly what causes it (Number of buildings, reaching 20% on Stage II, ...) It happens no matter what type of Biodiversity I complete first, be it arid, wetland or flower fields (with the bees). Restarting the game does not fix it (except if I start a new game, but then it reoccurs after a while).
I play on Windows 7 (64-bit), Version 0.31. Just in case: Does it matter, where the game is located? I'll try 32-bit and my Linux-Laptop if i get the chance.
That aside:
Not sure if it is intended, but while some buildings "update" after you change something around them, meaning if you excavate a new river-bed the water pump fills it, calcifiers, toxin scrubbers and, most importantly greenhouses do not. For calcifiers (they don't convert greenland to stone if water spreads further through their radius AFTER they are placed) it makes sense, as it allows me to control how much stone I want to have (only in some cases though, if they are built at the end of a river or water is still busy spreading). But for greenhouses this is a little annoying, because I have to finish building the toxin scrubbers before "greenifying" everything, which can be fineky if I run out of cash meanwhile. (But it's not a big issue once you realize it :) )
Anyway, thank you for reading this lengthy essay, and keep up the good work!
EDIT 1&2: No difference with 32-bit. It happened BEFORE I reached 20% progress, it is not reliant on the building. It can be "fixed" by restarting the game (which reverts thelast move, smarty you) and performing a DIFFERENT operation. But the chances of it happening seem to increase.
EDIt 3: Admin changes nothing. At some point you get stuck because performing any one operation (building something) gets you stuck. It seems to obviously be on my side, because I didn't find anyone else with the same problem.
