Super awesome idea, I really enjoyed it! There was a bit of difficulty at first because player 1 and 2 have different views. Apparently where I could see the menus, P2 can't, so I just had to verbally communicate switching players/starting the game. It might be good if possible to make it a vote mechanic with both players clicking "Ready" to start, or "Switch" to switch? The game said "You died" to player 2 and "Game clear!" for P1, and it sort of locks you out after you get to the ending screen, so a "retry" button might be good.
I also think it'd be nice to either do separate lives or maybe a "Follow the leader" mechanic, where the follower's lives don't matter but the leader's do. Would make it a fun opportunity to learn patterns without making the other player beef it because you're bad (ME, IM BAD LOL)
The music was super jammin and I loved the art! A multiplayer entry must've been a real challenge to make and it was super easy to connect and play, so thank you!
(Special thanks to Rosy,who played this with me today!)
