I absolutely loved Escape Goat, and I am happy to see more of it now. Escape Goat 2 is basically more of the same, which is not a bad thing. It offers a nice balance of platforming and solving intelligent puzzles. The controls and mechanics are just great. Really nothing to complain about here.
The difficulty is very low in the first few levels and always gets a little higher from level to level. Nobody should have any problems getting into the game. And yet it is quite challenging later on. Escape Goat 1 offered some high difficulty levels after beating the campaign. I expect the successor to offer the same (I didn't beat it yet, so I just can assume it will).
The main difference to the first part is the graphics style. Instead of the basic pixel art we got in Escape Goat 1, this game now uses a new high definition graphics style, which many people will like. I personally prefer the old art style, but I am fine with either of them. The most important thing for me is, that the controls didn't change at all. Despite the new graphics the game feels absolutely like the first part. Not all games manage to do that.
I like it a lot. Both Escape Goat games are real indie gems. You will enjoy your time.
