Level 51 is annoying like hell. I supposed all those 10K+ score is possible but you got to have lightning relexes to attain them. (my score is 6674 at level 51)
This game runs very slowly and conversations are accompanied by slow lips movements. The puzzles are not difficult to figure out, I am rating this a 2/5.
Easy to get full upgrade in Mission 1 and after that the only thing that could kill you is by falling off the platform.
Should have provided the option to buy extra lives though. Not a bad game overall, 3/5.
