I really shouldn't be loving this. It's only because of how reminiscent of Mario it is. The medals are waaaaay too hard. I mean, you don't even get one for completing a zone! It just isn't that satisfying of a game for me. I still think it's a great game! It's extremely creative, just super frustrating.
There were always different enemies and environments. I only knew I would die a lot and never get any medals. I can tell you there isn't a medal for not skipping the cutscenes. My favorite was probably the cloud level. This reminds me of "Enough Plumbers" with how blatant of a Mario ripoff it is.
