Thank you very much, I'm glad you enjoyed it!
I don't currently have any plans to expand on this game. Hopefully, the errors didn't hamper your experience with the game too much.
The first two errors are oversights on my part and the third one about exiting the game only works in the downloaded version and does nothing in the browser.
Unfortunately, I can't locate the files for this project anymore so it will have to stay as is.
Thank you again for the feedback and for playing!
