Evade - an ascii game for the Hackaday 2018 Badge

This is the music I have come up with for the Evade game's splash screen.  It might me a little bit too fast.  It is quite repetitive.  It comes in at 1313 bytes.  I am going to have to pepper the code with some keyboard input checks to provide a break out of the splash screen during the playing of the music.  Otherwise you have to listen to it until the song starts over.  That is not too long, but I know how things can get.  I want you to be able to get on with the game as soon as you would like.

Copy it.  Load it into your 2018 Supercon Badge and run it.

Please let me know what you think.  I am going to add it to the main part of the program in a few days so it will blend in with the splash screen.  

The lines 160 through 330 are supposed to be like percussion.  The limitation of the tune command gave way to what you hear.  I did try other things and like this best.

As for the tempo, I am thinking about 1/4 slower or, perhaps 1/3 slower.  It was not what I figured it would be when I wrote it originally at twice the tempo.  That was way too fast.

One of the suggestions I received from @Ian Weber and my kid (his girlfriend) is that the ion cannon was not loading fast enough.  Further testing was that the cannon is now done to 45 from 100.  Line 3310 has the variable y as the timing for the cannon to recharge after firing.

Speeding up the cannon to fire caused a need for the enemy ship to seem a little slow in its erratic evasive movements.  I adjusted that to 35, line 3330.

If you have played the game on your 2018 SuperCon Badge you should have noticed that the LED glows green to show you that the cannon is charged up.  When you press the fire button (space) you will see that the green light goes out as the HUD shows in the upper right corner that the cannon is now recharging.  If you make a hit on the enemy ship you might see that the LED flashes red for a brief period of time.  Sometimes I don't even notice it as I am too focused on the display screen.

Still working on the music and the instructions page.

I've uploaded the current Evade game text file.  It plays fine.  I still have to add the music which I started composing last night.  Figuring out how to break out of the music to get to the instructions page is proving to be a little challenge.  It may take a bunch of gosub calls or make the song shorter and repeating. 

I also discovered that I don't like the instructions page which is right after the the splash screen.   I am thinking ASCII at the top would look OK.

Let me know what you think about this game?  If you have hints about being able to break out of the music, I am all ears.  :-D

I think all I have to do is compose the Splash Screen Music.  The the code will be done.  :-D

I spent some time creating a nice looking splash screen.  I may add to it a little bit.  I tried using red as the lettering and it doesn't show up bright enough for me.  Perhaps my batteries are getting low. Here is code for the splash screen.  It says to << press space >> at the bottom of the screen.  Well, that will only clear the screen and get you a prompt.  Look at the code to see what I have done here.  Copy it.  Edit it for your own projects.  If you have suggestions on how to make it smaller, I am all ears.

 I just tested, and I am not absolutely sure, but, I can put all of the chr 205 (or whatever number) on one line.  That would be like: 10 chr 204 chr 205 chr 205 chr 205 chr 205 chr 188.  I really like that for making the code not be so lengthly.  It also crunches the line numbers.  :-D

I just checked the bytes free as it stands right now and there are 8923 B free.  <<12/18>>
