Hey, cool game, works well and is like an arcade coin machine game indeed.
While it is donkey kong -like game, it has it own nice spices on the playable banana split.
I would change the monkeys sounds to fix 8-bit theme, and then make the barrels more weighted and heavier on rolling. This could be playable on the mobile devices, while you can click the edges of the screen to roll barrels and by double tap to bam.
Good luck, this is a great Jam game. Hope to see it somewhere in the future. Don't make it to remind too much the Donkey Kong though (yeah, well... - lol)
