For me, Pandemonium! is better than the others, is a long game, funny, colorfull and not easy especially in the final levels. The levels are well desinged with no fustration areas. CK 2 is very 16 bit style and Bug loos ugly for me, not a fluid gameplay.
I am actually shocked that Pandemonium is so far ahead. I was expecting more votes for Clockwork Knight 2. Shame Bug Too! is so low on score, having completed it this year, I actually think it's the best of the 3.
My son and I have put a lot of time into all 3 in the last 5 years but mostly come back to Pandemonium. The original Bug! game mind not the 2nd one. Using the B.A.B.Y.S.E.A.L.S cheat opened it up. Clockwork Knight we completed and quickly forgot, though it gets played now and again in here just for the musical opening on CK2.
But Pandemonium gets the most play here. We use the 'ALMABHOL' password for level select and 31 lives and play the favored levels for time-based personal scores.
I think the gfx have stood the test of time pretty well.
Thoughts, prayers and other pointless platitudes are the establishment's way of saying 'tough sh1t'
Haven't played Bug Too (though I was not a fan of the original), between Clockwork Knight 2 and Pandemonium I would probably pick Clockwork Knight, the art style is quite unique and it plays quite well.
