Very pretty and polished animated sprite art! I really like how the characters look and the environments are a good match.
Audio is great, the music matches the pace and look of the game, and there are appropriate sound effects associated with every action.
There's a solid showcase of the mechanics to get players thinking about the different types of interactions the game may have in the future. I don't mind the lack of downwards or upwards attacks, it sort of gives the game a "beat 'em up" feel. Enemies feel a little too durable at the moment but are not that dangerous due to the stun and knockback mechanics, which de-incentivizes players from wanting to fight them. A map may become a welcome addition as the island grows. The stomach inventory is a neat concept. The controls are good and the attacks are satisfying.
Very nice work getting all of this stuff working and looking this good in a single month!
