Thank you so much for the feedback! Most of those have been fixed or updated in the latest Patreon version, including the h-scene sfx which got a nice overhaul.
I'm not sure what you mean about the save & load section though, I don't know what "forward 10 at a time" means. Forward 10 pixels?
For the BIRD cards, I'm unsure how broken they are but we've overhauled the SMS date system in 0.09 which adds static levels, zones, and a 5 star system that you receive based on how well you've succeeded. Those stars are then used to unlock stronger zones and you can only really get full 5 stars if you take- I think it's 10% of your health in damage or less. BIRD cards won't be able to prevent incoming damage.
