Dungeons of Dreadrock

Wow. Excellent game, with a full storyline and everything. Plus, the ads don't just appear in the middle of gameplay, which is quite nice. Puzzles are fun to work through, and there is a popup if you are small brained and get stuck (like me) One thing of note: On the multi chapter levels (where you have to swap between levels), you usually end up having to watch ads a bunch of times, which is a little annoying.

It's got good puzzles with variety. However some puzzles will frustrate you because it either relies on fairly precise controls with a clunky swipe system, or just a design oversight. I still have no idea how I beat the final boss. Sometimes you're asked to notice a TINY detail on an already small phone (yikes). Occasionally the unskippable ads are 1+ minute so I can't recommend watching them to support the creator. Still it's got interesting moments.

I can't believe this guy made 100 unique puzzles based on pre-established mechanics. Every one felt solveable, even using the (very useful) hints made wish I thought a little more to figure it out. I figured out after 90 levels that the ads are skippable after a few seconds, tap the edge of the screen and the skip button appears.
