Nice game. To my personal preference, the transition between the top-down RPG style to vector art is a little awkward. I liked the boss much more than the "regular" level. I think the main issue there is that there is no way to go in the middle of the group of enemies, where most of the collectibles are. So, you just need to hang around until they move enough, and it's a little tedious
Overall, a nice done game!
