Touhou Luna Nights is a mostly fun, but also at times very frustrating game. The game revolves around two main mechanics: time stopping/slowing to avoid attacks and enemies, and the graze mechanic from the mainline Touhou games in which you get as close as possible to enemies/projectiles without getting hit by them. Grazing gives you back magic and health, which is vital for the boss fights especially since you need magic just for your basic attacks.

Conceptually, the game is fantastic. The controls are great, the time mechanics and graze mechanic are implemented extremely well, and I assume the story is fun for fans of Touhou due to all the characters that appear (along with their themes of course) that I didn't understand because the only thing I know about Touhou is bullethell and cute girls in frilly dresses.

I say conceptually though, because while the skeleton of the game is good, the meat of it is a bit on the lackluster side. Level design is pretty basic and uninteresting, with the later levels just shoving annoying enemies and hazards everywhere. It's not terrible, but Super Metroid this is not.

The game shines with its boss fights, which are animated beautifully and have some really crazy looking attacks, but I can't help but feel like sometimes they were just too tanky. The final boss especially got tedious with how much health it had.

The game also features a level up system and a shop, but both of these are so inessential that it's easy to forget they're even there. I'm sure leveling up more and getting some more shop upgrades can make some bosses a bit easier, but hardly enough that it's worth the grind.

Overall it's a fun game, but probably not one I'll be returning to anytime soon. Best way to sum this up is really great mechanics that are unfortunately trapped in a decent-mediocre game.
