I feel like the reverse gravity aspect of the wildcard shapes are intended to be beneficial, but I'm finding that they inhibit more often than they help. They tend to wedge the larger shapes between the static roadblock shapes.
The wildcards are used for unlocking any part but also to unlock parts that are locked in the upper sections of many puzzles. These puzzles will start to appear in the second month (may).
I don't like that I have to have Shapik stand near something before I can tell if the mouseover will change or not. If he walked faster I wouldn't mind this so much, but I don't like walking across the screen only to discover the thing that I thought he should walk to wasn't something he could interact with. Very nice and atmospheric game, though. I hope the full game will appear on this site.
I've been playing this off an on since it was put on the site, and I just now realized that you can click on a clue in the game to get a description of what that clue icon means.
It's a grinding game. You'll either get bored doing the same levels over and over and quit, or you'll give in and buy creds to buy this game's currency to buy better gear.
No levels need actual guessing. Anyone is free to post a screenshot and prove me wrong of course
