The girl is very very cute. Kudos to whoever drew that. Love it a lot. The gameplay is also nice, giving me a good vibe of a collectathon platformer, which I solely missed. The levels are nicely designed, and the controls are very smooth. Got to the end quite quickly and its such a shame there isn't more to it, but I guess we are don't have enough time to do whatever we originally planned.
A bit of criticism I'd say the biscuit-collecting part is a bit hit or miss, as given how lacking in space the sack is, it not even worth it to put any biscuits into the sack. Just put down the sack near the end, go and collect every piece of biscuit in the level, and finally move the sack into the end will 99% give you three stars, and it feels like it's defeating the purpose of the game. I would also say lacking a title/landing page and an ending page makes the game felt less polished that it should be.
Anyway still, you all still made a good game in the jam, well done!
