Surprisingly great fangame.
Reminds of the flash era. I wouldn't be surprised if you were a dev then, given the stickmen sprite for Millie.
Guns were fun. Handgun was probably the best due to damage and range, but I liked using the minigun instead because the slippage sometimes go around the corners of the platforms.
Metroid style maps works. I was surprised to find the map was randomly generated, but that was a much appreciate feature.
The challenge of the game comes with range. You lose range when moving, and you have to move to dodge attacks. A lot of attacks go through walls, but most of them don't fade out like your bullets do.
Because of this, I felt the beam was one of the best powerups, because it let you deal with very inconvenient enemies through walls.
That said, you bullets do hit enemies offscreen, which is much appreciated, simply because it feels fair, and proves that Journey of Calamity doesn't play by the same "restrictions" as most flash games.
One very solid mechanic I'd like to highlight is the graze. For those uninitiated, graze refers to when a bullet just nearly misses you. Unlike Touhou's graze, which just provides points that can later be redeemed for an extra life, Journey of Calamity's graze adds to your special meter, allowing you to use powers like nuke, shield, invicibility, attack up, etc. That creates more of an instantaneous gratification than touhou imo.
God Sees All music was great. I didn't tire of it, despite how many times I reset.
Is it just me, or does Millie speed up when not in combat? Good "Quality Of Life" Feature.
Pixel art and general art were kawaii. I appreciate how expressive they get. Dull-eyed Enna... eroi...
In conclusion, should you play this game if you don't know what a vtuber is and don't care about Millie? Yes. The gameplay is certainly enough to sustain it.
