I have saw AmigaBill on Twitch. There was a few questions about..
the music:
The music and sfx are mostly from Unity3d Asset store. The Title Music is "Procedural Ambience" (
https://assetstore.unity.com/package...e-4414#content).
The battle music is "07_Space-Time_Vortex" (
https://assetstore.unity.com/package...s-pack-1-25686)
Jetpack:
(Sadly) the gameplay speaking against that.
Grenade:
Why not?
We will see..
