Clearly (from the fact it's "Einstein's riddle") a very old riddle. Not even a very good one. I've heard BS like "hardest riddle ever", but if you want the hardest riddle ever, check this out: http://en.wikipedia.org/wiki/The_Hardest_Logic_Puzzle_Ever
Is the tutorial battle supposed to be a crushing defeat? Start of battle he had 95 health and 21 power points, I had 100 and 20. First round. He uses a skill. 53 damage. I use a skill MISS. Second round. He attacks. 8 damage. I used a skill. 9 damage. Third round. He uses a skill. 53 damage. I'm dead.
No way to replay a level? First level I killed everything and unlocked everyone. Second level I wanted to test the chicken's ability to fly. Being a chicken and therefore unable to defend myself, I flew over the whole level. Now I can replay the level to unlock anyone.
Is it just me or is there ALWAYS a car or spike strips in front of the highway signs, making it impossible to kill choppers without dying in the process?
As far as spot the difference games go, I find few which actually *remove* the difference after you spot them. They just circle them or, worse, hope you remember which you've already clicked. Loved that aspect. Also- very cute story.
Matches the game description perfectly, so I can't exactly rate it too low. Although I'd like to see a bit more lemming and a bit less idle. ie- better graphics and some form of "gratz, you sat here for 15 minutes. go get a life" system. 3/5 for only being squares and not lemmings.
So sentinels are absolutely worthless. I measured my combo per second before and after adding 15 sentinels. Exact same. Only difference was my game started lagging like a beast.
Possible glitch: I notice when just hitting space to swing the hammer, turtles almost never get stuck on my launchers. If I mash on space impatiently, turtles seem to slow down horizontally and have a chance to bounce infinitely on one launcher.
Sorry, you can't use "www." as it may offend people. I haven't ever been offended by the statement "awww..." before, much less URLs. Anyone here ever been offended by a URL?
Fun concept, but too easy and too short. I suggest a version 2 with more ways to screw with your mind. Suggestions: different gravity directions in different worlds, doors in one world which affect OTHER worlds, puzzles that require rewinds (you drop down a pit to enter a door, then rewind to get back up while staying in the new world)...
