Honestly, this sucks :(
One thing that all the successful console ports have in common: They share the same playability mechanics, rules and fun factor. One thing all flash versions have in common: They all suck just the same.
I'm sorry, but I will be blunt and truthful here. This game is nothing like what you would find on a major console, say, the PSP port for example. I don't care what anybody thinks, but I'm comparing this to a major port, because this is what it SHOULD be like to deserve to be called a tetris game.
The PSP version has these basic, essential rules/features that all console versions also have:
1 Ability to hard and soft drop with up and down respectively
2 Controls that make immediate sense
3 A fast paced gameplay
4 5-10 seconds freedom to move a block when it's touching another block or the floor
5 A fun factor that makes it possible to play for hours on end
This game lacks these basic rules/features in these ways:
1 - No hard drop, WTF. There needs to be a hard drop or else the gameplay will be way too slow, without it, the game just seems blah
2 -The controls are just retarded, controls should be - A,D, for movement; W for hard drop, S for soft drop, Left/Right to rotate counter and clockwise, a HOLD button (Enter, Shift, or up arrow), and an ability to change the controls via the menu
2 cont. - If you have a problem with WASD, (B1kMusic.newgrounds.com/news/post/60 5996) here is a news post I made, it includes a download for an API file I made called key.as, it has clear instructions for integrating and using it, making WASD so much easier to do, now you can't say that you don't know how or don't want to do it.
3 - The gameplay is so slow it's boring, like the guy before me, the line clears should happen in 1/4 to 1/2 of a second, and multiple simultaneous line clears need to happen at exactly the same time, not consecutively, the rush of getting four tetrises is gone when you have to sit for 15 seconds collectively waiting for every line to slowly fade away.
4 - There is no freedom, the second the block touches the floor or anything beneath it, it automatically connects, making it impossible to get out of a situation where the blocks are built high, stifling the gameplay tremendously. There should be a 5-10 second delay if action is taken in attempt to maneuver the block, this makes it possible and fun to play the game for hours on end. (This is the biggest problem, by the way)
5 - There's no fun factor, buy tetris for the NES, N64, PS2, PSP (via PSN), Wii, etc and study everything about what version you got that makes it fun as hell to play and try to implement it. One tip is to insert quick, flush sounds for events like hard drops line clears and tetrises to make it more exciting.
Also - No elaborate or red backgrounds, it's distracting, a simple, plain, navy blue background should be just enough to make a decent background because it's dark enough not to strain the eyes and it's not distracting.
One more - File size is ridiculous, I was sitting in awe by how long a TETRIS game was taking to load, maybe get some smaller songs, and limit it to three.
For posterity's sake, I'll mention a flaw in the PSP version: there is no endless mode, no matter what you do, the game will end at some point because you won.
People: don't tell me to try to make one because I know I can and have made a tetris game, the reason I don't make one is because I don't fucking want to, it's a pain in the ass! But that's no excuse for this game to have these flaws and be like every crappy, boring flash version of tetris. This game could look just like one of the console versions and still not be fun unless you take these pointers and implement them, but for now, this game deserves a 4/10, that is my honest opinion. Play a legit tetris game, and then play this, you'll see what I mean if you're paying attention.
I do want to see this game become the first flash game to really feel like a legit tetris game, and this is why I reviewed. I'm a huge fan of tetris games and I take it seriously.
