This game is really nice ! I like how you were able to make to make such colorful and varied environments with only 4 colors, good use of patterns. I was so happy when I find all the pirate ships.
There are so much different antiques to find. I wasn't able to find them all... but still filled a good part of the museum, and enjoyed reading the little texts.
Some feedback : the player doesn't know he has to press A to interact with NPC and other elements, I think an input prompt would help. Also at some point I went too far and it took me a while to find the TP again, mabye a map, or just an arrow to avoid getting lost. I also find a glitch to escape the bounds around the museum entrance, but I think you should keep it, OOB is fun.
Nice soundtrack, but my favourite detail about the audio is the different walking sound depending on what tile you are.
I'll come back to play after the jam, I'm hyped if you add the things you had to cut off after the jam.
Really good job !
