Thank you for playing the game. I'm so happy to hear that you liked the game so much!
For the audio I was planning add some, but then I just simply ran out of time. (The quick solution was to add the splash screen at the start.) But now that I think it, yeah the game needs audio.... I'm pretty confident that I'm going to add some sounds and maybe even music to the game soon.
Getting feedback like this really makes my day and motivates me to keep developing games... Truly means a lot :)
