Very fun little adventure and all the pixel art was fantastic; the character portraits next to the text were both helpful and adorable. The credits were great too.
Sometimes the game would lag a little when there were a lot of enemies on screen, but honestly that's almost part of the charm when building for the GameBoy. Also, it would have been nice to see a health bar for the bosses to give an indication of progress, but all the fights went pretty quick anyway.
I've put this on my handheld emulator so I can enjoy it on the go. Great game!
