This was nice!
First of all the shift was very well executed! The sudden shift in tone and gameplay style was a sudden surprise, and the dialogue was well done.
I admit I'm not a huge fan of frustration platformers, I find them more just "bad" than "so bad its good". Though I also admit this one had more to it than many others I played. Notably the progress wasn't reset with the collectibles, and the restart was instant.
The art is very well done and looks nice, though to be honest I don't know how "so bad its good" it is. I mean definitely the lack of animations and the constant dead stare from the characters is funny, but it looks almost too consistently cute (especially Jeremy) to be truly janky.
I ended up getting the beanbag ending which was very cozy and nice. Felt far more heartwarming than I expected for a SBIG game.
Overall, excellent work!
