The world is large and non-linear. You'll find yourself using warp points to move around, and thankfully there are plenty so backtracking is mostly reduced to a minor chore. One quibble is that the map is a bit confusing - areas are delineated by numbers, but it doesn't accurately represent the world in a visual manner. There are tons of secret areas to be discovered, many of which can only be uncovered once you acquire new boss forms. The game's size isn't expanded too much by the selectable characters - there are differences, but you'll only want to play both if one playthrough wasn't enough for you.

The complete package looks and feels polished - the simple 2D graphics are colorful and manage to cram tiny details into the DS screen, while the controls are as tight as you would expect from a Mega Man game. After all these years, its amazing the formula hasn't strayed too far from the original. This feels undeniably like Mega Man, yet the depth continues to improve. Whether you own every Mega Man title released or if you want to reminisce about the good ol' days of 2D platforming, ZX Advent will fulfill your boss-power absorption needs.
