Interesting start to what could be a decent "rage platformer". The levels look really small at first, but after experiencing a couple of the troll platform moments they actually feel nicely sized for players to memorize the trick within each one. 

There's lots of ways that this style of game could be done and I'd recommend honing in on one of them and going full tilt with it. 

For example, one method would be giving some visual hints/tells for which block are false blocks (some effect playing on them, or a flicker every couple seconds, or something that could be caught by the player if they're paying attention). That method gives more player agency and lets players only have themselves to blame if they mess up. 

A very different method would be to just embellish the troll nature of a platform that just disappears and lets you fall to your death. That method plays up the moment with some whacky visual FX and goofy audio when the platform checks out and better sells the comedy of the moment so that players don't get as angry with the game when those kind of moments happen. What you've got right now seems to lean this way, but could definitely go more over-the-top with the comedy of the moments you've created.

Fun little game! Wish there was more. Is it possible to pass level 5?
