Oh man, that was super charming. Didn't expect a silly game about sentient PB&J to be so well done!
Super well put together platformer, that's absolutely oozing with personality. Good choices and use of sound effects, and though the music broke for me shortly into the game the SFX carried it the rest of the way. The sprites were well made and cute (I'm loving those butter slugs).
I was concerned at first that the platforming felt a bit slippery (I mean, Jam is sticky right?), but it never got in the way, and the levels are well designed such that I never had to do any super-intricate platforming with them.
Overall a really high quality game! Very nicely done.
