Thank you for your kind words. Over the last few days, I have been trying to get the build into a functioning state and I have fixed a few issues (like the coaster not being visible), but now have discovered that there are even more problems :( . I'm sure I'll get it working eventually.
I've got the working game on the original page now if you would like to check it out :) Once the voting ends I'll put the working version on the original page as well.
