I picked this for my Arcade spot for my Retro Achievements spot. I ended up picking Jack Skeleton due to the friend that suggested to try it. It was a fun little game. I kinda wish I had a Virtual Boy to play this legitimately. Falling down to the next stage would of been cool to see. But the game is comprised of little levels that you need to collect keys. Either through a puzzle or by killing enemies. The bosses are a dps rush until you run out of time. And you also collect stars to bank screen clears. The final boss has two phases and the second phase is hectic. Jack Skeleton is a melee character and this made it tough. After I beat it, I tried the rest of the characters and they both have range attacks. So it seems my friend had trolled me on my character choice.
In short, its a fun little puzzle arcade game.
