I like the overall idea and the art you have here. I got up to 20/15 a couple times. I'm not sure if the plan was to have levels on reaching the goal, but after the big mammoths came it seemed about impossible.
The mammoth corpses having physics makes this a bit more difficult. That may be intended, but it definitely can make movement difficult.
Well done !
I wanted to introduce levels of difficulty but I ran out of time. I had a choice between a fairly easy game or a challenging one and I thought it wouldn't be fun if it was too simple.
Good remark, one quickly finds oneself blocked by the pile of mammoths. One improvement that I also didn't have time to add was to disable the dead body physics.
