Amblik 2: Revoked

A spider-crushing game built on one long path rather than a single screen. You swing a hammer with the left mouse button, and scroll left and right along the map to meet what is coming. Amblik 2 leans on its upgrade system: four improvements in total, one that applies itself and three bound to number keys so you never have to stop swinging to open a menu. That one decision — hotkeys instead of a shop screen — is what keeps the pace up across a long run.
