I love the first four levels... But for some odd reason I find myself unable to allow myself to play a level after getting hit once. The first four I all passed on my first try then all of a sudden 5 came and it took nine. Then after that I couldn't get the next two (with lasers it was because the 'laser's were to difficult to tell apart form the inactive and growing lasers; I even almost got it once just to get hit on the very last push halfway through a full burst that would have ended the level.) (And the other 'side to side' I always did alright but at at least one point in the some odd hundred times you have to go up and down I would hit a lag spike and either go to far or not far enough... I know it's not how the game was meant to be played in both a glitch and design way but I'm disappointed non the less.
got to what I thought was the 'last bit' and I noticed a seventh 'hidden' option beneath all the others (cinematic mode only). In an attempt to utilize it I got ten trancendace, ten might, ten creation, ten summons, twenty joy, and one-hundred+ joy. Then when I clicked on it all other options faded (just like when you activate something) and i waited... and waited... I even left and came back (at least ten minutes had passed) the game was not frozen as the screen still moved and buttons still clicked, but the game would not progress. Refreshing the page it wanted me to start all over... Disappointed that I didn't even get to see the regular ending...
It's fun but it seems to have the same problem that every other game like this has where when you play a few 'near impossible' traps will be created due to bad timing of other traps. They are rare and sometimes you can pull through, but I always feel created when I move out of the way of one block, just to be killed by one I couldn't see do to the last trap.
I tried it and kept getting annoyed with the pacing. One miss an you have to start at the very beginning, which can sometimes be 10 plus seconds of either straight or sub straight blocks. Then at some points you will fail on a straightway and you don't know if it was the game not matching a tick (slower computers only) or if it was you blinking not a seizure thanks to the pulse technicolor backgrounds.
