It's a Sokoban game, where you as a robot pushes crates and pair them in 2 to make them vanish, instead of the classic Sokoban where the crates have designated locations.

There are many levels, so plenty of gameplay. There are a 3 star earning system on every level to add some competition and replay value, and the levels get quite tough and interesting at lvl. 30-31, but before that they are kinda boring and repetitive.

The movement system is the biggest update, the controls were very chunky and lagging which resulted in many players falling into holes or moving a box somewhere not intended. Not it's smooth.

You can complete the levels without buying helping items ingame.

Doesn't differ much from the other versions, but I'd say it's a tad better than the other two.

Price; I don't mind the dev adding microtransactions to earn a little, especially since players don't need to spend money ingame to beat the levels.
However at a starting price of 9.99 £ this game is in my eyes overpriced compared to what you get.

There's a limit of steps the robot can move, you can buy more steps with candy, which you can earn or buy with real money.
I find the limiting of steps a really bad idea, as it limits the amount of trial and error of approaches to the puzzles.

Levels could be much more thought through, it's close to the same level as the kids version. Only a few levels past 30 were enjoyable.

The music is not recommended to listen to for too long.

It's not a complex game, it could very well be a mobile game. Most of the levels were boring, but there are a few good ones, but not worth the price - Would be okay if you got all 3 of the games included -
The dev responded to my review of the Abrix for kids; and I take the major update as the dev listening to the complaints and advice of us players. I respect that, and I therefore give a thumbs up.
But give it some thought before you spend 10€ on it.
