This is a terrible continuation to the series. New levels have terrible design, far worse than original series. There's new level in this game, calles "robot wants justice", it's by far hardest and least fun to play: enemies just don't die unless you manage to knock them off to lava after 50 attempts, it's unclear how to defeat bosses too, level design is not near to the original series. It's not "I wanna be the guy", it's a silly robot game.

But it's not the worst part of the game, the worst part is the in-game shop. You would think you start with all the levels and can play original series right from the start? No, you are able to play a worse and smaller version of 1st game and only that. After you clear it, it turns out you won't have enough coins to buy another game in the shop and you have to repeat the level. Quite fun, right, playing the same level twice? After that you can buy new game. Either classic version of 1st game, harder "remix" version, or new, "easier" and worse versions of 2 other games. And the worst part is that you can only buy "robot wants puppy" and "robot wants fishy". If you want "robot wants ice cream" or "robot wants Y", or the new "robot wants justice" you have to get to them, and you won't know what you'll have to buy to get to them. And even then, you start with buying smaller version and collect coins to buy classic version of games.

It could be tolerable if at least classic versions were available outright, but developer doesn't know target audience.

tl;dr
New levels and new version of old games are terrible, you can't play classic games right away, have to spend hours of grinding. Just download and play flash games, don't buy this game.
