Thanks for the feedback. I am really glad you liked it, even with all of those things that may have taken away from the experience.
Some of those bugs, I really don't know where they came from, but I will look into that, and about the menu thing, I wanted to add a level selection menu for exactly this reason, but I was short on time since I had something to do in the last day.
I am really glad you enjoyed it, and thanks so much for the feedback!
