Even with those unfinished-related disclaimers, this is pretty dang cool. The only thing that's really missing is sound effects, and the map and Reimu's sprite look awesome. Gameplay works just fine too, the only adjustment I would suggest is giving the enemies less health but making them more dangerous, as combat feels like spamming hits until they shoot, then repeat. Oh yeah, and that thumbnail is rad.
Will definitely play this again after any updates.
