Tetris attack (panel de pon) on easy difficulty, the soundtrack is absolute catharsis,

It gets intense when the screen starts to fill, can give you that jolt of adrenaline (it can be a really intense jolt, that soundtrack gets intense), but you’re not in any real danger of losing because it’s so very simple. Swapping the blocks gives a very satisfying swish sound, the bubble popping noise as blocks remove themselves, the character noises as the combo counter goes up.

Poochy imo is the best character, but all of them have great backing tracks and unique combo noises.
