Please excuse me, but the #*@! Explorer always puts the headers in Italian
and I haven't yet found a way to change that...

I like the new colours and hate the sounds... :)
Advice: always try to include a decay in the volume of each sound effect...
that's what I've done in Oystron, and I think this makes them sound better.

Be careful, I've been hit before I could take off from the platform. This
shouldn't happen...

I think that what is really missing is the retro-rockets fire, especially
in the landing phase... ok, I know it's difficult! :)
Maybe you could use the player's missile for this, making it wider than a
missile, and shifting it a few pixels back and forth, up and down from
frame to frame. Don't know if it would look like fire, but it might be
better than nothing.

Also, you need the spaceship explosion. If your kernel can't accept
animations, try background color-cycling...

You're at a very good point with the kernel, soon the game will need fine
tuning so you'd better find some free time :)
