This felt like a real gameboy game! The opening looked very true to the gameboy splashscreens and all that. it reminded me of the boxing game that came with my gameboy originally! the sound is perfect. the music is super well made and sounds like legitimate gameboy soundtrack.
There was a lot going on at the beginning but I had fun figuring it all out. But I had to try combat a few times until I realized how to properly attack. Other than that it was really fun!
