great artwork and music on this game! they have a nice creepy vibe and hit that Game Boy vibe pretty well. i really like the concept for the game!
the player character and basic ghosts are real cute! nice animations on the sprites too! i also like the background in the first stage a lot. i agree with some others that the backgrounds are a little too busy and can make the sprites difficult to see. it might have helped to put an outline around the sprites just to separate them a bit from the bg.
i had fun playing, but i only got to stage 2. it’s kind of tough! i think i would have liked the attack to have just a little more range so you don’t have to get so close to enemies to shoot them. also it might have been nice to have ghosts wait a few seconds before moving when they appear to give the player a bit more chance to see them. not a big issue though. the biggest issue i think is that getting caught between ghosts is very difficult to escape from. a second of two of invulnerability and being able to move through the ghosts after being hit could help with that.
overall really nice job on this game!
