Playing without reading anything sure was a rollercoaster of emotions, it was overall fun and for some strange reason I wanted more.
1st game - felt a bit empty, and hitting an invisible wall made me think I broke the game.
2nd game - was a bit too long
3rd game - I just wanted to loot those boxes, barrels and chests!
4th game - Didn't think to collect the poop asteroids the first time around so avoiding all of them was ..uh.. impossible :D
I got to the end, but I was asking myself if there should at least be some statistics shown at the end like spores consumed, hit by spores, apples eaten, pipes hit, hit from bat/skeletons, asteroids hit, asteroid consumed/hit, times died, time to finish the game.
