Hi Rubenuxo!
I have to admit that, as a professor, I feel like I failed to do my homework by looking into similar games before starting. I had Geometry Dash in mind (I'd seen my nephews playing it, and it seemed like a good starting point), but Bit.Trip Runner is definitely the giant of what I was trying to create.
This might sound strange, but I'm actually glad I hadn't discovered it earlier, because I probably would've given up before even starting!
Thank you for introducing me to it! At this point, I feel like I can study it and learn from its mechanics without feeling too intimidated by it. I bought it on Steam, and I'm planning to play through the whole thing.
This was a really valuable discovery for me. Thanks so much for pointing me in that direction!
Best
