Create enemies with Aseprite (overarching)

[TSherpa10]

Create enemies (32x32 canvas) using Aseprite (or other software). This includes

• Enemy animated sprite (frames) - Idle, Walk/Run, Death (question: do we handle this with a quick animated sprite, fade, etc)
• Extra: attack sprite (question: do we handle this without an attack sprite?)

This is an overarching ticket so many people can assign themselves to it, then post updates either here (recommended) or Discord.
