Very nice game! A simple mechanic that was executed well! I really dig the idea of generating levels based on the music being played. I tested out a track of my own as well, and the process was rather smooth!
One thing that bothered me a little was there wasn’t much indication of where enemies were coming from, and, as such, I think I died a couple times because I was being attacked by an enemy from behind, but never realized it. In fact, I believe I had one run where I died without ever getting any score, most likely because an enemy was behind me killing me.
Another thing I noticed was while the procedural generation being based on the song is a great idea, the generated levels, at this point, all have very much felt flat. Not many features were generated. I’m very much impressed by any form of procedural generation, and what’s in the game works well, but it just felt flat over all.
Regardless, the game runs very well, and is enjoyable to play to try and get that high score. I also really liked how easy it was to add my own songs to the game with very little work!
I know I messaged you about this, but I did stream my time with your game. You can watch it here if you’d like.
