BIG THANKS TO SEBASTIAN BRAUNERT who the patience to deal with it and put music on it!
This was done using AGDxMini (by Allan Turvey) a derivation of AGD4.7 (by Jonathan Cauldwell)

and... sorry but i have no idea from where Sebastian took the music...

Nice looking game, but the music sounds a bit off. There are two sound routines running simultaneously, both trying to write to the AY registers, which causes it to sound stuttery. I found this POKE which appears to fix the problem:

‭POKE ‭33968‬, 195

By the way, the music is by AL and was taken from here.

this graphics looks like it's possible to scroll it in smaller steps almost without the attribute artifacts

I like it! It has limitations due to AGD and character movement but still it creates a generally positive experience.

I agree that smooth scrolling of the mountains in the background is doable (not sure if with AGD) and would make everything
look better.

Neat. I've only managed checkpoint E so far, but it's going on my SD card for later!

Nice one. I must be tone deaf; I didn't even notice!

Gab, I assume this happened because AY Sound was set to ON in the AGD options. If you're adding your own AY music then you need to set it to OFF. Also, is it okay if the version using djnzx's POKE is the one we add to the archive?

Really good fun, but no scoring at all?

surely there is a way to get a nice scrolling even with AGD
Allan Turvey showed some very prominsing results in the past but i do not know how that is possible
Anyway i tried using blocks but since the whole game is based on blocks usage, I was out of bock and coul not create a nicer scrolling (the mountains actually scroll relying on two strings of blocks which are drawn to be 4 pixels away from each other)

This is an AGD mini game so each sprite is 8x8... however each sprite (which are left empty, not drawn) puts 8 or more blocks around itself to create the different things you see in the game (the tank, the enemies even the bullets are blocks so to avoid the typical grafix corruption you get when sprites and blocks collide)

for some reason when i tried to add scoring or even checkpoint messages (you know with all that stuff about timing etc ) everything crashed
I tried many times and in many different ways but i guess i wa asking too much to AGD... maybe
