Theme-wise, this game transcends the jam theme a bit, but there are still things suddenly failing (and falling) in it, especially when it's yours truly's turn to play. :) If I would be exposed to the game without the presentation outlining the background, it would probably be impossible to figure out the meaning; however, I would probably end up worrying about how to balance a roll on a tramway positioned on pair of shoes rather than the back story. :)
The game is pretty challenging, with the challenge well disguised as peaceful zen tower building. It feels like a sandbox-y "toy" at first, but there's progress and (intrinsic) measurement of success. The additional mechanic of some items occasionally trembling forces player to remain vigilant, and it's often the player, not a quaking piece, who ruins the construction.
The means to deliver this player-driven experience are concise and functional - there's nothing superfluous, everything has its function, role, meaning. The art resembles collages from the 1960s-1980s children books, matching the theme in surprising but working fashion. Sounds provide additional feedback and music fits the theme, the additional effects of trembling items (paired with sounds) do the good job in notifying player.
I have to commend the physics of the items - it's well set up, collision envelopes are detailed (yes, one can put roll or fork into the cup!), and whenever I destroyed a growing tower when frantically attempting to stop trembling alarm clock and cell phone, it never felt like the game's fault.
The minimalism in GUI is generally very healthy, however, there's probably a bit too much of it in "Nevadí". I would recommend adding basic GUI "wrapper" allowing to pause, restart or exit the game. :)
"Nevadí" nicely demonstrates the merit in Bohemia Interactive's design motto "Simplicity is the ultimate sophistication". Thank you for this challenging, frustrating and addictive little gem.
