.T.E.S.T: Expected Behaviour Review (Goblin)
It's in beta right now, but I like it so far. The puzzles range from being extremely easy and sometimes almost an insult to the user's intelligence, to requiring Garry's Mod-like physics glitches to solve a single puzzle. It's got a lot of talos principle in it, the rules are firm, all the puzzles are logic based, but at the same time there's some room for creativity. It's not as pretty as portal and the story isn't as good (so far) as portal or talos, but its a good mix of both.
I don't like how short some of the puzzles are, some are just "Grab a ball and go through a door" I'd really like some longer interconnected puzzles, which I am really looking forward to them including in the final version.
Personally I want a puzzle game that makes you think for hours, and find new ways to stretch the limits of the rules. This game has the potential to be that. 1/3 of the way through the game I've run into 4 or so puzzles that are gonna stump a few people, I want to see more of those. It looks like it could really have a few thinking puzzles and I can't wait to see what they have. Going to be definitely worth the price when it comes out.
EDIT: Upon completion of the game, The ending is anticlimactic and terrible, but the puzzles are fun! Definitely a great game.
