I'm gonna ramble off a bunch of reactions to the first hour or so of me screwing around and not knowing what I should be doing.
The ghost that gives you your head, you initiate your interaction with it using B (Fire), but you use A (Jump) to choose the head. That seems unintuitive and inconsistent.
Why does the character stop moving when you press B? Is it an aiming mechanic? I don't think I've found a weapon that uses that, and having my character stop when I'm still holding left or right is kind of strange.
The whole movement feels laggy. It might be the early build, but I've been killed several times by an enemy that should have been an easy head stomp. Based on the gameplay style, I expect something as simple and fun to control as Super Meat Boy, but this little guy's fighting my every command.
The only weapon I've found so far that seems to do much of anything is the ring of explosions around my character, and there's always a gap in the explosions to my right. Even if I'm facing left, the gap's in the same place, on the right. Usually that's right where the enemy I really want to kill is. Is that why? Is someone messing with me?
Quick note: I'm using a Logitech gamepad with Joy2key, so there's a chance the way I've mapped my buttons might be off, but I don't think so. The game's playable the way I've got it configured.
