You can die to the boss when its in its death animation which I did accidentally to the second boss.
Gameplay was fun, and liked the part where when it went to a new scene it would do this alternating thing with the colours as if it was loading it in.
I'm sorry about that, I only had the time and mental stamina to make sure the lasers clear upon boss defeat.
Thanks for playing! I'm glad you had fun. The screen fade outs were all planned then made by hand, meant to simulate how the game boy would flush a scene when transitioning to something that's a bit intense on its limited memory.
