I had to put the assets folder in the src folder.
I actually like the dissonance of the title theme, the actual game music loop isn't nice to listen to lol. I'm not sure what I'm supposed to be doing? Destroying the flower things I guess. It seems like my fire effects proc at random? I killed the first two I think. Moving around the map is also very clunky imo but it adds difficulty.
I'm not sure if this is actually beatable because as you say on the game page I don't think your ability works unless you get enough speed, which some of them you can't build up speed before they kill you, I think.
