Suggestions needed for my tower defense Steam Capsule

Hi everybody, I try to make this short but no promises 😅

Summary: Im developing a tower defense gamr and need your auggestion on how to design the Steam capsule.

Towers and enemies: In my game, both towers and enemies are regula human. Enemies are people who used too much of a special rnetgy drink and now are mindlessly grind and hustle. Towers try to disrup their pattern. There are 8 different towers: a grandma who throws pillow, a salsa vendor who throws salsa a dj who slows enemy with music, an artist who throws paint, a philosophy proffessor who immobilizes enemies with exsistantial quesyions, an ice cream vendor who generates money, an IT technician who damages enemies with EPM and another tower who throws something else (as sniper)

Environment: city street, farm, shopping mall etc.

Problem: the functionality of the towers are kinda the same as other tower defenses yet it's different. So its hard (at least for me) to show tge genre of the game in the Steam capsule as the towers dont shoot any bullet and there is no explosion so its hard to communicate the idea of tower defense to viewers.

I already designed a Steam capsulr but cant upload any phoyo in this community and not sure if I can share the link from another community where I have the photo.
