What I would love to see in the game is the actual level number the player is at. When you show it to others (regardless if it's live or via screenshots/videos), the number of the level you've managed to reach is definitely something you could brag about!

Going to repeat my request for a speed mode because I think it's a good idea.
Perhaps also a tutorial page that just explains what each of the upgrades does.

The speed mode is a consideration but how to communicate it effectively to the player - as well as how to judge what's a good speed for each level.



In terms of the weapon upgrades, start a topic here and I'll pin it to the top :D

Remapping of controls?

The keyboard controls or Joypad controls?

Joypad in my particular case.

.sid music support, customizable for each level. For old times' sake.

Hehe, I love that idea :)

And the title music too, in that case. That Steve Turner tune so belongs in this game XD

A sound queue would be nice when a particular power-up is highlighted so that you don't have to take your eyes off the playfield.
