Its a pretty fun game that does feel like your exploring unique areas with a really nice visual style and music.
I do think however the game could use some sound effects. its interesting that only the dash has a sound effect and no other action does like jump or collecting a recon point. Also the purple mushroom area is a little slow, maybe add less hidden paths (but still keep them cause there still interesting, you could even give the hidden tiles evaporating a sound effect to create like a chain reaction of sound effects).
Also the game doesnt really seem to care if you collect one or multiple recon points, you can leave the area all the same. Maybe just add some reward system for collecting more? (though it makes sense if its a game jam and you ran out of time to add something).
Finally, maybe make it so you can talk to some npcs more than once. Cause there was this one guy in the mushroom village that said something about his son that i skipped by accident and then couldnt go back to talking to him.
Overall game does have potential, i think the style is quite compact and colorful, just make sure to polish.
