What is it changing?

https://steamproxy.net/sharedfiles/filedetails/?id=2302308845 https://steamproxy.net/sharedfiles/filedetails/?id=2302308609 the yellow one happened suddenly during gameplay and the other one was after quitting out of a level.

I'm an indie developer who is a big fan of this game, I spend all my childhood enjoying it, without further ado.. I made a game inspired by it. and it's totally [free] https://steamproxy.net/steamstore/app/1602330/ACROBATIC_CAR/

While in main menu there is no sound at all (should it be?) After pressing Play SinglePlayer game is frozen forever until I close it with Ctrl + Alt + Del. It's not how I remember the game from the childhood :/

Basically just want to ask the development team, if you're planning on adding more official level packs, like Quick and Easy and Quick and Hard? I know you've added Lost Internals, and, although you haven't added it (yet), OLP is floating around out there as well, but both of those have been around in an official capacity for many years, and have been played relentlessly. If you have any such plans in the pipeline, could you enlighten us with a potential planned release? Thanks :)...
