This can be considered one of those "falling block" puzzle games.
Tetris, Cleopatra's Fortune, Columns, Lumines, Puyo Puyo, you get the idea.
I like the genre, but this game is bull ♥♥♥♥.
Okay whoa whoa WHOA. This review just got off on a horrible start.
I mean for crying out loud. Bull ♥♥♥♥? That just ain't the right thing to say about a videogame, no matter how much I dislike it.
Let's back the truck up and start over.
AVSEQ is a audio-sequencer-puzzle-game. It's comparable to REZ (in the loosest possible sense). It's the kinda game you're supposed to play until you lose track of time and/or space. The day you quit playing a good puzzle game is the day your body quits on you.
Let's start with what AVSEQ does right.
-The concept is fine. Match colors to create fragments, collect enough fragments to unlock notes, collect enough notes to complete the level. If the colors fall too far you lose notes. Simple & effective, this is proper puzzle-game design.
-In terms of playability, the game is functional. It's not like I suddenly lost control of the mouse or button clicks refused to register.
What AVSEQ does wrong can't be adequately explained with bullet-points. Early on the game is in-offensive. This is a term I use to refer to "easy, boring, but still adequate entertainment". There is some satisfaction in getting the MAX color chains, and I don't know what else to say...it's pleasant to have around? After a few levels however the game turns into an RNG-fest. Falling-block puzzlers always have a bit of RNG to them. They work because you don't know the solution, yet you're given mere seconds to find it. AVSEQ starts becoming bull ♥♥♥♥ is when critical power-ups start appearing....and you need them.
It's easy to become overwhelmed in this game, so wouldn't it be great if a power-up that slowed everything down happened to appear? Look at that! There's one...and another one...AND ANOTHER ONE! Holy smokes you've completed the stage. Now wouldn't it be awful if a power-up that sped everything up w-OH GOD you just got a long series of them! There goes all of your notes, time to restart the stage. If you miss anything in this game, you're done for. You have the highest chance of success when RNG favors you. There's no rhyme or reason to the system. If you're doing poorly, you won't get bailed out by slow-downs and pauses.
But this isn't how the game gets you. The most frustrating aspect is that the cursor isn't large enough. When I'm trying to move from one end of the level to the other to catch those falling colors, there are no second-guesses. In those frenetic situations, I don't want to think "did i click on that color?" I don't have time for confirmation, because I'm focused on the next move. Due to the tiny cursor I start asking myself the wrong questions, and losing. This is what a bull ♥♥♥♥ game is all about. The slightest fix would make a dramatic improvement, and make the game far more playable. Instead, it practically forces the player rely on RNG in order to succeed.
And if all that weren't enough, in terms of audiovisual design, AVSEQ isn't any good. For a game that offers too-high-to-be-a-real-number musical compositions, you'd expect to hear a single memorable tune. Instead, everything sounds assembly-line bland. Half the time it sounds jarringly out of place. Towards the end of a level, when the colors are falling like heavy rain, the music sounds so down-beat and dull that you just want to lie down and sleep. The visuals are a stark contrast, since they're loud and obnoxious. This is the perfect combination for losing track of colors, visual aids, and everything necessary to play the game at the high-level it attempts to demand.
Look, I gave this game the old college try. If the RNG hadn't decided to stop doing me favors, I would have gotten all of the achievements. I'd still feel empty though. Is hitting a brick wall for a few hours worth it? Probably not.
