The game was awesome, the game felt very polished, the graphics vere awesome and the game was very fun, especially since this game like to play with the players expectation A LOT!! Good Job!! One note I'd give you is that, and this is a thing that i noticed even when developing my game (Which they are similar btw, I'd love if you'd check it out :3), even if in you're game wasn't a huge deal, swapping up/down deepening on the current gravity is a big unintuitive and a bit confusing to use :/
Another note: The spikes in level 2 that moves on the conveyor belt they are a very nice and clever idea!! What's not very nice it's the unexpected block that falls in level 3, i thin you should shart with at least one block already fallen, so the player knows exactly what to expect (and not left confused on how to progress)
Also, Ye, We like Partric around here!! (^D^)
