Thanks for your feedback! We didn't go too hard on this game jam since it was our first so a lot of it was just building the game itself and most of the levels were actually implemented in the last few hours. We definitely would have enjoyed more levels, and may do a rework/continuation in our spare time since it was just a cool idea and we thought it turned out well.
Options/settings were also something that got thrown to the side in hurry to complete it, but definitely a smart move. Also will keep contrast in mind for future games. Glad you enjoyed it!
