I noticed I forgot to submit a comment on this one. So I will after have about 5 hours to thing about this game.
The game was really nice looking I love the art style. I wish there were more checkpoints dotted around so I wouldn't have to do the hard jumps again because I died to a bullet I couldn't avoid because of the angle I needed to jump.
The music is very good! I really love the gba style music.
Whenever a bullet was fired the game slowed down a lot and game play felt really muddy and slowed down but as soon as the bullet disappeared it would speed up cause me to fall off ledges a lot. I didn't really feel the theme throughout the game at all it was more a quick beginning cutscene.
Overall I liked the game couldn't finish it because of the performance causing the gameplay to degrade. Other aspects were good though! Nice game!
