Hi. I'm glad it worked! I was honestly not sure at all it would. Cross-compiling is hard. I did consider making the portraits pixel-art as well, but I feel high-resolution pixel art is actually harder to make look good than traditional art. Maybe it's more of a question of making the game's art better in general. I'll try to add a tutorial for the next version; I'm aware the controls aren't very intuitive.
You're right, most people don't play shoot-'em-ups anymore. Alas! I really like them. They have a specific design philosophy to them. Part of why I'm making this is because I wanted to have a more intimate knowledge of how they're made. Anyway, thanks for playing! (I tried to play your game, but it crashed when I pressed the start button. Probably a local issue. I found the descriptions really funny, though.)
