It's a nice game, hard and frustrating sometimes 🙂 thanks for sharing it for free.
Here are some possible improvements:
- "return to ship" objective : we didn't even get out from it first ! Game may start there from going outside the mothership,
- explosions could be better (asteroids split looks weird, specially in your own video),
- sounds volume cannot be defined
- thrust upgrade not displayed on diagram
- thrust made no sound 🙁
- UI cannot be used with keyboard
- maybe a velocity meter, just for fun, could be useful
- I get the bad luck to get spawn very close to a big asteroid, a "safe spawn radius" may be nice (if not get out the ship as point one)
Finally, is there any save/load feature ? Doesn't look so, it would be great to add one (file or code to type like old games)
