Definitely try Samorost 3 if you like this one. The puzzles do get a bit more obtuse but the art is incredible. Most of Amanita Design's games are incredible. The best ones are Machinarium, Samorost 3, Botanicula, Pilgrims, and Creaks, in that order.

Thanks! I do own Machinarium already! @AlasEarwax

No problem! Machinarium does have harder puzzles, but there is a useful hint system if you get stuck. Hope you enjoy it whenever you get around to itv :)
