This game does on-screen virtual buttons in a satisfactory manner, I haven't played many games like that but I found the controls good for an iPad platformer game. You jump with the B button and fire with the A button (and you can drag the A button up to fire upwards) while moving around to dodge enemies and projectiles, jump over pits and collect stars and skulls. There are tons of levels and tons of things to unlock.
I'm terrible at stealth games. In metal gear solid, I constantly have to shoot my way out of failed sneaking operations, and I don't feel bad because even tho it was ridiculously tough to win such encounters in the old MGS games, the recent ones - such as peace walker - left you with good options and choices in case you knew you had to fight at one point or another. I've heard many good things about Mark of the Ninja and decided to give it a shot.
I'm not going to be too hard on Maple Story, its roots date from 2006 or something that old and the game truly evolved through the years. Everything about it got better over time, from how classes started out - at first you had to roll randomly your stats and then fight for 10 levels with a really weak and boring character, while now you just need your core stats and you can skip the tutorial - to the distribution of quests by levels, to the 'balance' of skills to the amount of bugs and random stuff broken here and there. It's not really a good game even tho the concept of MMO platformer is pretty unique but I've spent way much time that I would've with this game during many years.
