Well well, if it isn't Shibey's game. Really impressed with what you've done, as usual... The gameplay is pretty tricky, you have to dodge bullets while aiming with your mouse and chaining together enemies, which isn't all that easy; bullet players will know your central vision tends to be mostly locked on your own hitbox. But the challenge is what makes it so fun! Did I mention, not one, but two puzzle bosses? SunnyChow's music fits really well too. I'll be back when the full game releases :)
PS: My speedrun strategy is to get up close to every enemy and take them out with rapid fire. This is also a fun way to play.
