Alright, this is quite a neat game, which hearkens back to the 16-bit/32-bit era of 2D platformer games. Presented in a retro 4:3 aspect ratio (which my computer monitor is, which I prefer), it also has scanlines to enhance the nostalgic, CRT feel to the visuals.
You can cast zip lines to prevent from falling, as well as for climbing to higher platforms.
I find Steel Assault to be rather difficult. You have an energy whip to lash enemies, and can also punch them when up-close. It seems that I just have to die constantly until I figure out the attack patterns of the bosses and mid-bosses because it is pretty unforgiving.
So far I’ve only made it to the 2nd level. Very hard, but fun game. Fortunately, this game is available on Steam OS, so it runs natively on my Linux desktop computer.
