Alexey Pajitnov (designer of Tetris) and Markus Persson (designer of Minecraft) were kidnapped because they were supposedly collaborating on a new game. Instead they were working on a miniature robot that was a blend of their two computer games. Tetrobot was activated in their absence and had to go rescue them from "The Boss." Definitely cliche.

As Tetrobot, you start out only being able to jump but quickly get a drill attachment. With this drill you are able to drill and collect certain blocks in the level, similar to Minecraft. Throughout the game, a couple of upgrades are added to Tetrobot to allow it to drill and collect different types of materials. With this collected matter, Tetrobot can regurgitate the blocks onto the paying field following a couple of rules:
1) The first block must be anchored to the level. It cannot just be put into mid-air. Subsequent blocks must be attached to blocks currently being placed.
2) Groups of four blocks must be placed. No more - No less. This creates "Tetronimos" I-J-L-O-T-S-Z.

Collecting and building platforms to get through the level is the goal. There are couple other things such as undrillable blocks, falling blocks, slimes and TNT. Each level also contains a Treasure Chest. Collect this chest and bring it to the level and you collect the "Block That Matters" for the level. The blocks that matter all pay tribute to different games.

Finally, every level has a star available. If you finish the level with a set level of blocks in your inventory you get a star, i.e. finish using the minimal number of blocks left on the board. Finish at the minimum get a gold star. Finish below the minimum and get a green star.

Rescuing Alexey and Markus will probably only take 3-4 hours. One of the Steam achievements is to complete this part of the game in one session. However, to get 100% (all the BTM and stars) will take significantly longer. I have played about 15 hours and still have 16 stars to collect and 14 bonus levels to complete. This is a fun little puzzle game that can provide a casual distraction to full out rage quit.

Blocks that matter tries to be a puzzle and platformer game and is mediocre at both.

The primary puzzle aspect involves collecting blocks and placing them again. This simple concept is ruined by needlessly convoluted rules about how you must place and pickup blocks. The most basic moves take too long, its not fun and place one wrong block and you have to reset the whole level, redoing sections you've already done.

The potential of this game might be better realised if the levels were shorter or there was a rewind button.

The story is boring, irrelevant to the gameplay and relentlessly unfunny.

I would not call this game casual as indicated in its 'tag'. It is too fiddly and unforgiving.

Only buy when on special and if you're desperate for a puzzle game.

This game is great until level 29 of 40. Until that point it's a puzzle game. For no good reason level 29 is not a puzzle, it's a twitch-timing platformer. I have solved the puzzle, but because I don't have the timing down to the ♥♥♥♥ing millisecond I can't progress any further. It's ♥♥♥♥♥♥♥♥.

I got this game gifted, off the recent Humble Bundle, so maybe I'm not in the best position to review this, but you're reading this, so I already did. Deal with it.

I don't think Blocks That Matter are worth €5 of your money. Why? To begin with, it's not a very complicated game. It's a puzzle platformer, based around manipulating blocks, that might as well been a Flash game. But it's not a very well designed puzzle platformer either.

The "premise" of the game is ridiculous: two devs (who are basically Alexey Pajitnov, creator of Tetris, and Markus "Notch" Persson, creator of Minecraft; the game doesn't attempt to hide this) create some small robot who has to solve puzzles to go to portals and to then go to more portals and for some reason rescue the two heroes. (I didn't really pay attention to the story, it's a puzzle game.) Yeah, could do better in terms of plot development.

The Tetris and Minecraft references are very prevalent in the game, and by very prevalent I mean the core of the game's design. You got blocks. Of different types, which behave differently. Blocks, which look very much like in Minecraft. And behave quite a lot like in Minecraft. (gravel and sand fall down, wood and stone doesn't, obsidian is unbreakable, etc.)

And then you can use these blocks to build structures. But only structures shaped like Tetris blocks.

That's the game.

I'm sure there are more kinds of blocks with properties that I couldn't dream of (the game even shows me some of these new blocks I can't do anything with in the first levels of the game, as if to taunt "you can't do this yet! better backtrack later!"), but the gameplay is frustrating. I'm probably bad at the game, but to be fair, getting stuck in a level and having to restart it by manually killing yourself (or blowing yourself up, in this case), is not good design in my book.

The music is okay, the visuals are okay, but all this to me is a mix of two already-existing games, just in the puzzle genre. There's zero originality in this, and I doubt I'll play this longer, it's just not fun to do.

You can buy this if you don't mind all of the above though I guess. (especially if you're smarter than me)

This game doesn't have a checkpoint, quick save or rewind system, so if you make a mistake you have to start the entire stage over. The forums indicate such a feature won't be added. The game is otherwise fun, but unless you have lots of patience, I can't recommend it.
