This version requires more micromanagement to play but I like the degree of controls that are made available to players. The one thing I do not like is the lack of fast forward to speed up the time progression as provided in Pandemic II. Other than that, this is a solid chapter worthy of the Pandemic series.
Completed all 45 levels with bonus on. The trick is to win all levels with par first, then solve them with bonus on. This is a challenging game but certainly not impossible.
Got the easy badge and card on my second try. This version is much more CPU intensive than the predecessor (Can't seems to find the option to tone down the quality).
In any case, can't say I enjoy it more than the previous one.
To attain gold medals, the game seems to award you by taking the longest path available instead the other way around.
An odd concept which developer/uploader should have mentioned that in the "instruction".
A very nice sequel of the series. The puzzles are not too hard to figure out while the two paths are clearly marked which make replaying (to choose a different path) less of a hassle.
One thing I don't like about the sift heads series is that the mark (target) is often not clearly stated thus necessitates the old method of try and error; very unprofessional like of an assassin to be doing all those guessing work. Other than that, the game is still relatively fun to play.
Arcade mode stopped gaining level at 20? I wonder if it is a glitch? Anyway, I can't say I really like this game nor do I hate it. Just an average arcade shooter with endless enemies.
