What a super cute idea! Really enjoyed the gameplay, even if I think you can make it more challenging by increasing the difficulty over time, for example by increasing the speed at which the hunger bar drops, or by increasing the number of items and lowering the amount of wood in the final stages.
A detail I loved is the dynamic music that changes when each beaver dies, and in general I have appreciated the sound design. Maybe the death scream is a little too much but still a cool idea.
Great work!
