Seen this too many times. Random hidden traps are a tiresome game mechanic that is bearable only if your game is fun even when you are losing, for example because it is silly or otherwise endearing. This isn't one of those cases. I'd rate this higher if it was your first attempt at a platformer, but as this is a sequel i can't really say anything nice. It's a game, and you can move by pressing buttons, and it recognizes things hitting other things, but that's it. Sorry.
