Hey, thanks for playing! Glad you enjoyed it.
In the EA release there will be a different song per level of course, unfortunately didn't have the time nor money to get another song made for the second level in the demo.
Hmmm, I tested standard ultra-wide aspect ratio in the editor the UI scales to it properly but the effects don't, like the vignettes for picking up items or when you dash. I'll take a look into it. I don't have a ultra-wide monitor so I kinda just rely on setting the custom res in unity, guess it might not scale properly :\
Again, thanks for playing! And thank you for the feedback <3
