I’ve come across a couple more click adventure flash games. This type of game seems to be more prevalent on the web than I originally thought.
Samorost and Samorost 2 are two of the better designed click adventures that I’ve come across. They’re set in a universe where people inhabit small planetoids that resemble tree roots. The original suffers from a major flaw that afflicts this type of game generally. The inability to pick up where you left off later. Fortunately, the game is short. The sequel solves this problem by having level codes. In general, the games are fun to watch and easy to solve. They’re not major brain teasers, but they can be diverting for a couple hours. And you probably won’t be searching the web for walkthroughs.
The other game that I found The Quest for the Rest, a game used to promote the album Together We’re Heavy by The Polyphonic Spree. The background music for each level is a track from their album. Again, the game here is diverting but it’s not a challenge. Presumably, they want you to advance through the levels so that you can hear more sample tracks from their album. So, in that sense, it seems to be efective marketing.
