There's an old czech fan game I found again which is similar to both Liero and Worms.
played it a few years ago
it's real-time. i also translated it into english
https://files.steps.moe/worms/cesky/wormsrealtime_en.7zArrows: move or target (even on rope)
Enter: jump
Hold enter: jetpack
C: shoot rope (anytime)
V: dig ground (or left+right)
Ctrl+Left/Right: change weapon
Space: shoot (even on rope)
there are a few gametypes available. You can pick either a Liero or Worms style (inner and outer landscapes, where the "Mortal floor" acts like Water). There's a CTF too.
you can add your own soil fill, soundbanks, music
you can use any size for land (and window), but 800x600 is good
different weaps available etc...
pretty fun to try, what do you think?
