I really liked the progression here. In the beginning, it feels like you're going to get totally rolled by the biscuits. After some futility keeping all the baddies in line with punches, the ground slam technology gets revealed and you're able to make a lot more progress. The final form is definitely the best though. Breaking through the platforms really sells the heft and inevitability of your biscuit-eating event horizon. All the biscuits are gettin' in there and there's no way out of it at this point.
Also worth noting that chatty NPCs (or disembodied voices?) have the potential to be more annoying than helpful a lot of the time, but it definitely works here. Dialogue hit a good balance of entertainment, relevance, and brevity.
Good game! Had fun.
