Nice game! also local multiplayer was nice too! Its all about reflexes but I am not sure if it was random but felt like it opens the hole under player more frequently. nice touch to keep player moving. XD
I'd say, local multiplayer would be more fun if you could block each other's tile. would make it more strategic.
if you try my game, you can find a web build in the description. it has music as well. although you don't need to rate music. couldn't add that in time. ^^ thanks!
