Small update/fix

Lu[Idle]

Lu[Idle] is an Incremental game with Idle and Clicker elements as well as pixel art visuals and music.

In this tiny update/fix I changed an array having to do with the number that shows up when you click the code bar which now actually deletes the number after it fades away hopefully fixing performance issues. I also added art to the prestige upgrades. Make sure to give Lu[Idle] a good review if you like it :)
