Your comment inspired me to go back to the save in the 2nd episode where I was stuck not knowing where to go, and I ended up playing and finishing the episode just now. 3rd episode left.
I don't even really think the game is especially great, it's just a fun and breezy thing to play through.
Yup, beat the first episode. "Fun and breeze" is right, something about these simple games just feels good (even if the enemies feel like they're way too fast.)
