|This is my first actual attempt at beating the full game. Every level has at least one card to find in it, but some levels have 2, and there's no way of knowing. I did miss a few of the cards had to use a walkthrough on youtube to find them.|
The game gets kind of hard about half way through. The 6th world where you have to ride tiny blocks across lava is where it actually gets legit frustrating.. screw it, at this point I don't think it's worth my time to explore the levels on my own. I'm just gonna go straight to the walkthrough for these levels.
Those extra levels are all based on figuring out where to go. There are no enemies, and instead there are a lot of trap goals that you have to avoid to get to the real goal. This was the only part of the game where I used mid-level save states to save time figuring out where all the paths lead to and what not... but once I knew what to do I could beat them legit no problem.
The last stage is just a boss battle against the magic bag. I had to use save states to beat it the first time, but then I went back and beat it legit without savestates.
