Tried Annalynn ( Annalynn by Cruise Elroy , also on Steam) but bounced off it as soon as my retro-cute character’s overanimated head bounced off the platform above them instead of allowing them to jump through. Cute snakes spawned from the floor or fell from the ceiling right on me constantly, all in the first, two-screen-wide stage. I like the Pac-Man + Donkey Kong set-up, the embedded 960p vertical screen, and the low-res graphics, but author Cruise Elroy seems to favor restrictive, no-warning, insta-kill play, which is definitely not my thing.
