Thanks for the feedback.
Ultrakill wasn't the main inspiration for the movement, however it was the game that got me to prefer movement based shooters to other shooters.
I plan to make another game with the same movement code in the future, this game I just added randomization mechanics to help it better fit the theme.
The music is very bad indeed but I had to do short with the time I had.
Looking back, could have been better to not include music at all.
Thank you so much!
