Before posting a bug request please make sure you are using the last version of Pix64.
Thanks a lot. Yes the idea was to stay minimalist. This is good feedback about the doc I could put that on the itch page and in the readme.
Some good ideas there. The ability to destroy enemies I'm not sure but what is very good is the "glue" idea. This would allow the player to move objects. So yeah a movable color. You can use it to block enemies or change their path, destroy a barrier (maybe). But also it could block yourself if you don't play it right. Could open more puzzle possibilities to the game. Definitively something I will think about :)
This is a good idea but it would defeat the purpose of having all the game data on a pixel image :( I'm aware the sound effects are annoying though, I plan to improve them.
Another approach would be to store the sound effects as WAV files in a 'sfx' folder than Pix64 load at start up. You then are free to put whichever WV file in your local Pix64 'sfx' folder.
Will try next release, if I get time to do a next release ;)
You can run Pix64 (untested) using the following command within the Pix64 folder:
Normally mono is supported and installed by default on most Linux distributions.
Thanks for reporting that, should be fixed next release. As a workaround you can name your carts 'cart_01, cart_02..., cart_10'. This fixes the sorting.
