Quiz about energy
I found one error.
While this "game" offered knowledge I had previously not known, that may or may not prove to be useful, I find this work to be lacking. What I mean is that it isn't really a game at all, it feels like a tool that I could find on the internet to help me study for an upcoming test. It wasn't particularly interesting or unique, in fact, this very bland. If you wanted to make this into a game, I would suggest adding sound, some unique visuals, something that sets it apart from the countless online quizzes on the internet.
I don't want to discourage you from creating, but you need to put more work into your projects, this is far from a good entry, it just feels lazy. I would like to see you improve and create better content but unless you start experimenting with something different than what you have repeatedly done, you will struggle to improve.
This is totally boring though. I... I actually like tests but this one wasn't good. I didn't feel like I accomplished anything.
