Too much like button hunt. Being 9 years old adds sympathy to the people who rate the game, but it doesn't make the game any better from an objective viewpoint. Maybe when you're older, kid. You've got potential.
The last world's music and level design is an absolute torture to the mind. But I guess that's what you were going for, huh?
Aside from that, it's a nice little game.
Very glitchy for me, strangely. In the middle of the maze level I was teleported back to to treasure map level, and in the MS Paint level, just as I clicked the color pallette, I saw a few levels flash by and ended up back at the gun level.
This game features my video game pet peeve number 1:
It is not announced when invincibility is about to end, causing you to accidentally kill yourself as soon as it wears off.
Feraldis, you didn't play it for long enough.
It takes some time to appreciate the combo system, and it will take longer and than a day to see all the different types of enemies.
Not saying you should play it longer. Suit yourself. I'm just explaining why people like it, and you don't.
