This is great. I love synthwave. I love infinite runners. I love to "bang the head onto the table" games.
So this reminded me on sth. like geometry dash, but also on some old games from my youth which I hadded to boot from floppy disks. Super nice.
What I REALLY loved was the use of the sacrifice topic. That "upgrades" downgrade the game was also an Idea I thought about how to realize that. You showed me how this can be accomplished and I want to thank you for this. It was an awesome experience.
