Question: I play tetris attack on easy mode since it's speed is the same as Pokemon PL's timed attack's speed. Legit? or should I knock it up a lvl?
I am terrible at explaining things. If you have any questions please ask:
If you enjoy playing on easy mode and you don't take the game too seriously then playing on easy mode is no problem at all.
If you want to really excel at the game then I would recommend playing at normal speed and hard speed. The reason for this: it forces you to stop going for the first thing you see. Let me elaborate: sometimes the first chain you see might be doable in 7 moves (a move is pressing any button) which isn't too bad. If this is the case then sometimes you need to do 12 or 20 moves to continue a chain. This is very doable in easy mode, but if you are in normal or hard then it is a lot more difficult to pull off (unless you have GOD speed). So why play at higher speeds?
Playing at higher speeds forces you to continue chains that take as little moves as possible. Once the luxury of going wherever you want to connect your next chain is taken away your brain is forced to think in a different way. At first it is really stressful, but after a while you start to see more than one option for your chain. Keep it up and soon you will see multiple options for chains and be able to select which one would be completed in the least amount of moves. What do options do for gameplay?
Having more options means you can plan ahead further and further. Once you can see at least 3 chains ahead then you can start flying and clearing the screen off like it is nothing.
My recommendation is to do what you enjoy in the game. Playing on higher levels will only improve your game.
