Hmm, right after I posted, I found which box shouldn't have been checked. The bug is that it's greying out a compass that it shouldn't be, rather than that it's not accepting a solution it should be.
Level 83 has a bug. I've got a configuration where all of the compasses are greyed out, showing that I've met their conditions, and all remaining boxes are flagged, but the level is not complete. This is clearly a valid solution, so there must be something wonky with the way this level is set up.
It's really, really annoying that the game changes the orientation of the levels. If I mess up on a level and have to start over, this just means I have to do extra work to reorient myself instead of being able to redo the ones I already know for sure.
This is the most mind-boggling stupid "game" (and I use the term very loosely) I've seen on Kong in a long time. Why does this have a badge? You should be trying to keep people away from this, not directing them toward it.
It saddens me that Kongregate gives badges to pieces of crap like this. It's not even a game, it's just a pathetic click harvester. Things like this make me wish it were possible to give negative stars in my rating.
While I appreciate the desire for more Monument Valley, I think it would have been possible to create a game which still had the same mechanics, playability, and joy without so blatantly mimicking the look and feel of the game. I would hope that you at least asked MV's developer for permission to use their style for your game, though I suspect not.
I have now completed the badge, and I stand by my assessment that this game deserves one star. There is a difference between making a game challenging and making a game require millisecond precision and forcing you to repeat something dozens of times just to get the exact, pixel-perfect movements you need. This game was not hard, it was obnoxious.
I just want to say a huuuuuuuuuuge f**k you to the game designer for not putting even a single checkpoint in Certainty of Death, Small Chance of Success. It is so far beyond unreasonable that even though I'm 98% of the way to the hard badge, I'm considering just quitting this game.
Big bug: in Tricky Tavern, I got through Green Street, went to the next level, and then ended up inverting direction and falling back into Green Street. From there, there was no possible way to do anything except fall and die infinitely, and I had to exit the level. There should be a platform or something preventing you from falling back into Green Street, because then it becomes an infinite death loop, and I lost all the progress I'd made through the zone.
OK game, but could be better. I love some of the abilities on the components (the conversion on D3, the true vision on H2, for example), but it's terrible that you have to give up those abilities in order to progress. The later components are all focused just on the defensive abilities, and lose the good powers. Progress should be cumulative, you shouldn't be penalized for making it farther.
@bob - The reason people are complaining is because it's so precise, and so time-consuming to get it to line up exactly the way the game wants it to, when you the game only checks for completion if you unpress the mouse. So what might take 5-10 seconds of fiddling on Classic mode can take 10 minutes of click, move one pixel, let go, repeat, repeat, repeat, on pro mode. I gave up after two levels, because it was such a colossal waste of time.
Gets tedious and annoying, because the weapon upgrades just don't keep pace with the monster growth at all. Needs another level or three of upgrades available.
Low quality game. Humor is weak, and gets annoyingly repetitive very quickly. You have stars to collect that do nothing at all. The improvement of upgrades feels weak. The progression of levels is more about piling on more badguys, rather than harder ones. I'm only playing this to get the Kong badge, wish I didn't have to.
I like how capitalism is alive and well after the zombie apocalypse. "Thank you for saving my life, and for devoting yourself to cleaning up these areas and killing all the zombies. Want to learn how to swing a machete? Only $2000, cheap!"
