Thank you! I pretty much did everything alone other than music and sound effects. One friend helped me with some coding, but overall it was pretty stressful!
As for the other areas, not yet. I do plan on continuing this and fleshing out the areas now that I am not under a strict time limit. I agree there could be more variety. I actually wanted more enemies and background elements to make them feel better, but atlas, I was already running late in uploading this. I even wanted cutscenes and such. Also oh right, I did forget to put that, thank you! I am glad you enjoyed it!
