Thanks for all the valuable feedback, I'll take every point into consideration if I end up making a proper complete game. This prototype was simply to showcase what I have done for a university project but I do intend to keep working on it.
As I said, if this is a prototype, it's a prototype with progress. All games start somewhere.
I see potential in the project, considering you're also using an engine that helps with that.
If you eventually update the game, I'd love to test it and give a new review!
