There's 5-star potential that Rust Bucket can still reach, but until then, this game has to settle for being merely very good, though it could be one of the best roguelikes on the App Store at some point.
Rust Bucket is a well-designed mix between roguelike, puzzle game and turn-based RPG with a nice cartoonish presentation, although with little variation and some flaws in pace.
You might be tempted to play through most of Rust Bucket’s Puzzle Mode before diving into the Endless Dungeon, but I wouldn’t recommend it. You can figure out most of what you’ll need to survive after only a few levels, and the constant appearance of obnoxiously long ads might make it unbearable if you have to deal with too many of them. Instead, play a few puzzles and then jump straight into the Endless Dungeon – it’ll be a lot more enjoyable that way.
