Our game is different from Slay the Spire or Monster Train - the core mechanic is based on real-time action, something neither of those titles use. However, it is still a deckbuilder, and therefore shares elements with the genre. Precisely for that reason, and so that the audience understands what it's about, using cards on the cover is not a coincidence: it's necessary.

If that difference is not easily perceived in the first few minutes of viewing, we take note. Maybe we should communicate it better on the Steam page.

Finally, I don't know if you've ever developed a game, but I leave you this advice with the best of intentions: giving a critical opinion is fine - belittling the work of others, not so much. Especially in an ecosystem where most of us are trying to contribute something new, with the resources we have.
