Watch as your bullets pass straight through their legs.
-ABYSMAL IN GAME CHALLENGES
Can you imagine a game where our hero never got any upgrades? Imagine how boring megaman would've been if you never got a single upgrade. Some might disagree, but IMO why can't you have challenges that let you utilize the game's mechanics/upgrades. It's why time attack is such a popular challenge; Not "beat the level without using X"
No tooltip info when you click/hover over an available assist, upgrade, or enemy within a given level. That goes for in battle and on the world map.
-NO STORY ARCH
the game trailer does a better job of telling a story
-only 5 achievements
Great for people looking to add a perfect game to their steam collection. But from a consumer standpoint, it lowers overall replayability
