Not as enjoyable as K.O.L.M. or K.O.L.M.I.A.M.
"K.O.L.M. 2" is an enjoyable platformer, but it does not hold up well against the first installment.
In the first game, there are different ways to pass a room depending on the power-ups you possess. If you can double-jump, take the stairs. If you can triple jump, great, just go through the roof. In this game, the only power-ups that affect the game significantly are the light shield and the bomb. You access most rooms only once and never look back. The voice box is just another nameless trophy/medal/shiny star... that requires you to run around for no apparent reason. Also, does the little robot absolutely need the voicebox to get his sister attention? He is walking BOMB for Pete's sake. :)
In the last few rooms, with 2 characters at the player's command, I expect a lot of puzzles as clever as anything in "The Company of Myself." The end came rather abruptly.
After around 20 rooms, the novelty of the "blown-out", dilapidated, dreary look just wore off. More variations in the graphics?
[Not really spoilers] That cliffhanger ending is very classic. By classic I mean I've seen it on numerous occasions before.
The game fell short in various aspects. I enjoy it, but not enough to recommend it to anyone. If you've never heard of the K.O.L.M series, try "K.O.L.M.I.A.M." instead.
