I love the Console and even the GBA port of this game, but this version feels a little too chaotic. The furthest I got was past the first mini-boss.
Plus, why is jump and shoot inverted? Normally on keyboard the leftmost button (A or Z) is jump, and the one next to it (S or X) is shoot. I makes playing this game way too confusing at times.
I still like the games, but this first one is rough.
As for Ruffle compatibility on Linux as of writing: Everything works flawlessly, but on older machines the backgrounds don't load and there's a bit of input lag. Though, this seems to be a normal issue for Ruffle when it comes to older hardware, but it's not a big deal because why the hell would you be running Ruffle on a 2000s PC with a Core2Duo anyway...
...OK I would, but I'm not normal.
Edit: Someone pointed-out that there's only one stage in the game, so I tweaked the line that said I couldn't get past the first stage.
