Chain of Challenges, episode 32.
There is one good way to follow the Lemmy invasion of the previous challenge and it is the BASS.
Draw a sprite of any bass instrument as a game item. It can be an inventory item, a collectible, a weapon, etc.
A very short list of examples includes: double bass, bass guitar, guitarrón, tuba, sousaphone, basson. If you want to be original, do your own research. There are many lists online and none of them is ever complete.
You have to use the Low-8 palette by SoundsDotZip.
Bonus challenge: add animation of that instrument being played and producing those low note vibrations.
The challenge thread will have all the challenge updates. The thread is also a great place to post your WIPs.
