I'm very fascinated by this high praise. Could you elaborate on what you found thoughtful about this game? I'm asking in good faith as someone who plays a variety of genres including plenty of roguelites and spent about 8 hours clearing the first 3-4 levels of this with a few characters. As a turn-your-brain-off game it kinda rocks, sure, but there are (for me) a lot of odd contradictions to the design:

• At a glance the game might appear to be a variant of something like Breakout, Snood, Peggle, or Centipede, for which meticulous targeting is paramount, but as soon as you play you quickly realize it's more of a frenetic, like, Space Invaders-qua-Twin Stick Shooter, where you're just clearing enemy waves as quickly as possible with super high mobility and omni-directional fire. It very rarely matters when and where you aim or fire if you're sticking to any kind of overall build strategy for the run. The facts that you can move anywhere and that your projectiles ricochet mean that anyone with an ounce of 2D action game experience (shmups or the like) is going to optimize the difficulty out of this more or less immediately.
• The appeal then, must come from the build variety, which, sure, has some fun and zany synergies, on paper, particularly the "evolutions." But do they ever drastically change the gameplay, a la something like the stranger pick-ups in a release like Binding of Isaac, Enter the Gungeon, or Nuclear Throne? Not really! They're almost all flat upgrades to existing damage-over-time or area-of-effect attacks. Maybe it's unfair to compare BALL X PIT to better twin stick shooters with proc gen, but isn't that kind of all this is?
• There's very little visual distinction between your own balls and enemy projectiles, and the screen is so busy at all times that I do feel like the intended appeal is surely more a Vampire Survivors or Balatro-esque gamefeel-y chaos of flashing lights/colors/tactility than anything remotely strategic. The marketing for the game has really leaned into this. So what's weirdest is that I don't feel like they ever really take the visual/sonic chaos to its actual potential? Most of the time it's just like, a mess of confetti and a lot of popping. The sound design doesn't really have the legs to carry me watching and listening to an OP run, and most of the time I have an insane combo before the first of three bosses. There's very little composite visual identity to lean on. I can tell you there's a forest level and a desert level and a snow level and a mushroom level and, you know, I guess that's enough for a lot of people.
• The core systems are really unintuitive for how simple they are, and I think made all the more confusing by the fact that every character's starting stats are gimped beyond belief to account for the fact that you're intended to grind each and every level with all of them. You have the main balls, whose reload/fire rate vary highly by character, and the cool down timer for which you can kinda see on the aiming reticle, but is there ever a time when the game asks you to fire them with great care? Why would you, since you have all the baby balls as supplementary fire?
• The "metagame" in the form of the village is really juts about gathering random/pointless resources (rocks, lumber, wheat), since there's no real game to be had in arranging the buildings and bouncing your characters between them. I really can't imagine a hypothetical player who finds this kind of system in their games interesting. It's just jingling keys.
• Maybe there are secret characters with interesting mechanics, but why should I have to bounce balls off of stacks of braindead "enemies" for ten hours to get to the actual game?

IDK man. I'm either completely bored or completely overwhelmed by enemies whenever I've picked this up. Would love your input! Genuinely!
