Had a few issues with control setup, and for some reason I'm unlocking achievements when I shouldn't be, but other than that things are working smoothly.

When exactly does Steel Strider take place within Astro Port's Astro Saga? The store page says in the second half of the twentieth century, which is a bit unprecise. Does the game itself (or any other valid source) tell more?

Though I've been enjoying this game, I'm having touble with two of the achievements. "Bombastic" and "armor breaker" require you to score kills with the grenade launcher and rocket launcher respectively. I have been using these weapons repeatedly, as I find them useful against groups of enemies, but I have yet to unlock the achievements. According to the counters that accompany the achievements, I have scored no kills with either weapon. What's going on?...

missing a bunch of achievements including the one for beating the game and a couple of bosses theres another thread with the same problem from years ago devs said theyd fix it if theres some kind of fix id like to hear it

I press the LMB and I both fire and jump.
