This really has some simple but fun mechanics. I love having to do precision jumps and feeling a sense of accomplishment going down to get the picks.
At that point going up is a pretty cool move and the level design working down and upwards reflects the thought that was put into the level. My only gripe with the game so far is that the pick gameplay still feels a bit too sluggish for my taste. I loved the speed going down but moving up slowed things down considerably and I lost that momentum I built up, but that might be just me.
Overall an awesome experience definitely will buy the full version when it's out :)
