A good take on robotron with Touhou elements. Art all comes together and each enemy has its own patterns. Music is on point with retro style too. I like how the octopus level is actually better to rush for the rabbits instead of fighting them as their deflecting bullets get unmanageable fairly quickly.
For the theme, I like the interpretation that retro developers themselves are the legends of game industry, although I'm not sure if that was your intention.
Game seems to repeat after Wani Mob so I stopped after 14 waves. Definitely a solid jam game I'd recommend.
