Very enjoyable to play, my only issue would be if there was a restart button, when I realized I messed up and wanted to reset but needed to die it seemed a little time consuming to have to reload it that way. If the slime moved/ reacted faster I would have enjoyed it a lot more. It seemed to lag ( I do not know if this is because i played in browser ) but there seemed to be a delay in the feedback from me moving with the arrow key to when I actually moved The music was not invasive at all and had a nice feel to it, the puzzles are not too hard but some took me some time to figure out and I appreciate that. The tutorial aspect was well done and I liked how you integrated the two with out interrupting game play/feel. Keep up the good work! :)
