Hey i've got a laptop with similar specs im planning on using this software for a game im working on. I'm willing to help you debug it and all. lmk if your interested.
I like the bike mechanics I just feel that the UI and gameplay need more updating. But overall I can see you put a lot of technical work into it the past 12 days!
The tutorial seems good for the most part, but one thing I noticed that's a tad clunky is when you place the battery. Its hard to jump on the platform right away after placing the battery down.
