Personally I would've preferred smaller sprites in exchange for a larger screen space and there's a few levels where the grappling blocks were a bit hard to see but the platforming itself is fun so it's worth at least a playthrough.
Also be aware that there's a glitch with saves, before loading it you need to start a new game and get a game over or something along those lines.
