Thank you! You might be glad to hear this but I do plan on doing one more update adding more content and fixes... That music was made within 2 minutes and is 8 notes on repeat or so, it was the last thing I added and if that weren't the case I would have gone mad during playtesting haha.
Infinite mode sounds cool, but this is my first Unity game. Although I might have an idea on how to realize it, I'll focus on fixed levels first. Some more tile types to spice it up, which might need hand placing to function as desired. However I could look into the infinite mode only containing the basic tile types as seen in this version.
Anyhow, glad you liked it!
