2 things about this game really irk me: the window between falling off and not jumping far enough is too narrow, and the perspective is really bad. The game would be a lot more playable if you could see gridlines for the empty space, but right now, both level 49 and level 50 are enough for a 1/5 rating.
I had 3 glitched savegames - in one, I apparently accidentally blew up a ghost, who is now missing: http://bunnibunni.com/view.php?user_id=46808
In the second, I bought the necklace before getting the quest, which resulted in me getting the reward, but when I later loaded my savegame, I couldn't beat the quest anymore, even though Coriander was wearing the necklace; however, saving and loading after I got the quest resulted in finishing it.
There's also a third savegame, where I couldn't find Pirate Pete, but blowing up the forest that was in his apparent location solved that.
This seemed like a fun game - until I encountered the mess level. It's hard enough with just the rolling and bouncing blocks, but the blocks falling from the sky in random places make it nearly impossible. As it is, 20 seconds is 5 too much to is doable.
5/5? Really? The movement of guards and the target is too random to be able to make an actual plan, and their randomness hurts you if you're hiding somewhere and they check it 5 times in 5 seconds. Conversely, them not following the bloody footsteps leading away from their boss's corpse is also odd. It's a fun game, but these factor prevent it from being great.
