The game has some big issues. Onigiri is useless since it only heals 10hp making it way too expensive for essentially no healing. The only way to earn money is fighting the Susamaru clone, and only gives 100 coins when she is way harder than the original fight and it takes way too much food to be remotely worth the effort. the stat boosts don't apply during the fight making it way harder than it needs to be, especially since there is no way to upgrade your skills or attack power.
