Awesome, I'm not sure how you saw a bit of Elden Ring and DS3 in this but I couldn't be happier with that comparison as the souls games have been my favourite since I was about 13 (I'm 23 now) so thanks very much for that, made my day.
As for the advice... I have already made changes to the players movement to slow things down a bit, however I don't plan on adding checkpoints as I saw this as being similar to jump king where there is potential to lose all progress with one mistake for maximum intensity, but I have ideas on how the player could maybe rest for a while. I will consider checkpoints though if I feel my current idea isn't going to work out as planned.
The camera has also already been altered to where it makes using the look down less of a necessity and more of a luxury, and I plan to do much more strategic level design so the look up is also useful.
I've thought of adding enemies to the game and I like your idea of risk for reward with the reduced fall damage. The enemies aren't a sure thing yet but definitely up for consideration.
Thanks a lot for taking your time to carefully analyse and review my game, I really appreciate it and I look forward to the day I can release an update for you and any others that would like to try out a more refined version of my game. Happy jamming, take care :D
