Thexder and Silpheed’s origin was on PC systems but their gameplay seems strongly arcade-inspired. Both of them are brutally long and attritional, with no saves and with resources like health not fully recovering between levels
I eventually beat Silpheed when I returned to the game as a teenager – at intermediate skill levels, that one plays a bit like FTL or Downwell: where you repeatedly make it easily-ish all the way to the final boss but then get crushed there for lack of resources.
Meanwhile, the furthest I got in Thexder was around level 5 (of 16), and that already felt like a big achievement. The experience of playing Thexder is slogging carefully through a robotic hell with no end in sight, where a single error can leave you stuck in a corner to be eaten alive by a swarm of piranha-like drones
(A bit like Spelunky, to continue the strangely apt comparison with roguelites)
Looks like a Bionic Commando Rearmed type remake where they kept the level design and the core mechanics the same but added a lot of mechanical quality-of-life tweaks. E.g. in the original the health burgers do hurt you if you touch them instead of shooting them, and activating your shield drains your HP just at a slower rate than getting hit
