Oh my gosh, what a twist!
This game was super fun to play in both phases, and the art and music were both excellent. My one complaint was that I didn't realize that being physically unable to place any more buildings was the requirement to advance the game, which was a bit confusing. Had I not read the comments, I might have thought the game was just a cute dinosaur park-building sim with no proper way to end it when you're done. Overall though, I can't believe you turned out such a polished game with two extremely different mechanics in just 48 hours! Well done!
