I never played the GBA game before (or the game boy Donkey Kong game) so this was an interesting playthrough for me. I enjoyed it quite a bit! The music is quite chill and its pretty on the eyes. The puzzles themselves are a bit easy until you beat the game, then the challenges can make you think a bit. The first bit of it its just you finding the key, it was mostly a cake walk for the majority of it. After that it has you make your mario mini follow you with a key, those can be a little tricky with some of the level designs, but none of it is unfair, they're really good designed levels here! It's a decent time that would be a good pick-up when it goes on sale!
