Thank you for the thorough review I love to hear things that people are interested in from the players perspective. I will start thinking about the rotating platforms idea for sure, I do think using those as a timed launch would be great for a challenge level or even as a way to reach a secret area or something (maybe even a power up to let the player take extra hits). I have also considered checkpoints, or even an easy/hard mode where one has checkpoints but they can be removed for an extra challenge. I love the interactable objects idea, logic and physics puzzles are always fun and it would add that variety.
Animation updates are for sure on the list as well, I'm still trying to decide if I want to try and implement them in a way I'm familiar with (using the baked animations and just adjusting them until they match up with the game speed and things like that) or if I'm ready to start looking into unfamiliar territory with procedural animations. I know I need to start getting familiar with those I'm just dragging my feet lol.
Anyway thank you again for all the feedback, this has given me some new perspectives on the project that I think will really help. Good luck with your games as well I'll make sure to check out your entry today!
