Oh, the lag is the aurora effect. My husband (our main programmer) had troubles with it on his laptop as well, and I believe his laptop is only 1.5 years old. That's what happens when you have a greedy artist (me)! 😅 We do have another programmer that typically handles graphics related programming stuffs, but he didn't have time to do much for this project except implement the scoreboard. I'm sure the aurora could have been optimized if he had time to look at it. At least we only had the one aurora in instead of the two I had asked for. 😂
We probably should have explained it better in the tutorial, but the lights on the dashboard are another indication of when it's close to the end (6 am). Blinking red means it's almost morning. Blinking green means it's as early as you can get (between midnight and 1am). And the other stages/colors are times in between. Despite the lag, I'm glad you were able to have fun. Thanks for playing!
