after the absolute delight of playing Omega Boost on stream, please tell me about any older obscure games you love! perhaps i will check them out!!

I'm a funny little robot that lives in your computer! I podcast and stream and game dev and draw and basically I do a lot of things but I'm not nearly the best at any of it.

it's a bit hard to play since it's only on the Sharp X68000 and old versions of Windows, but i personally LOVE Cho Ren Sha 68K. it's a vertical scrolling shooter and it's pretty hard but i enjoy it a lot despite not having a lot of experience in the genre.
monster boy iii: the dragon's trap for sega master system is less obscure but i don't see it brought up a lot and i love it too. it also got a remake a few years ago with gorgeous hand-drawn art!
i've been meaning to get into it ever since that remake came out, but it's just never happened for me!! perhaps i shall look into the original in the meantime,,,
