Thank you! I'm glad you liked the UI presentation... I think I spent too much time in that instead of working on making better levels for the game though. :P
That icon with the bars is to display the player's best scores. Implementing an online leaderboard would've been too much for the game jam, but it's something I want to try maybe if I decide to develop this project further.
About the horizontal scanlines, yes others have pointed out it's a bit jarring. I'll add a toggle for it if I develop this project further, for sure!
Thank you very much for your feedback! :)
