I really like the concept, it reminds me somehow of slime rancher.
Its a good game and i enjoyed it but it really needs some balancing. The only strategy that works is going to the right getting 2 coins for 2 skeletons, going to bed and repeat, but upgrades are incredibly expensive. Hope you update the game post jam and make it easier, the game has potential.
Also, you can try my game if you want, it just takes 5 minutes ;)
