Hi!
I managed to finish the game and defeat the boss. There's a few points I think could be improved:
- Indicate somehow the goal of the player ingame (not only on Itch): if someone doesn't read your description, he won't know that he has to clear an area from enemies before moving to the next stage (a simple fix could be to add a counter on screen of remaining enemies for example).
- Boss battle is super easy, you should probably try to add a few mechanisms or patterns to the boss. Here you just have to run in circle and shoot and you won't have any problem handling the fight.
- UI is ok, even if I don't understand why the player's life is represented by a kind of mana bar (with mana potions that restores it).
- Speaking about the potions, you should allow the player to walk on them without collecting them if already full life.
- Pixel ratio consistency! I kinda dislike the look of pixel art games where the assets aren't having the same pixel ratio size (e.g. compare your player to the walls, it's very different).
- Last thing about the theme: there's nothing ingame implementing that, only your Itch description is mentioning some story about why you're there.
Regardless of those points, the game isn't bad at all. It's totally playable and enjoyable!
