Good ol' Comiket 80 era doujin game. It sure has the lack of visual polish of the games of that era! Weirdly enough, Touhou looks more polished aside of the character art! Yes, Touhou.
I like it. It's still fun to play anyway.
In a nutshell it's... ESPGaluda in space. That's... not creative, but hey, it works. Plus, when was the last ESPGaluda game again? No, ESPRaDe doesn't have the kakusei mode, okay? It's in the ESP series but not ESPGaluda series. You shoot, laser, bomb, and accel, the kakusei mode. No gender change here. If you're familiar with ESPGaluda's juicy cancels this game will be at home for you.
But in terms of gameplay 2 janky stuff stand out. First, Type C. Type B only looks ugly. Type C on the other hands, the options will obscure the main character's body because the color is exactly the same as her armor. That is not good at all! Second, Type A's bomb barely gives any damage! I'm not sure if this is by design or if it's a bug.
If you had been offered by a friend to "pirate" it, no need to be shy. Do it. The game had been distributed for free by the developers anyway. I heard the download link on their website doesn't work anymore. You'll have fun with this game.
I do think the replay glitched at the very end, though. Sorry for the bad recording...
