I tried some of your other itch games last night & can see that you've been working on some of these ideas for a while! I can see that the screen shake is actually toned down from previous games so that's nice. One of your older games was actually unplayable for me because of the shake. kafaildalf seemed slightly more severe than Apocalypse Angel too, although I was able to play that one. I can understand leaving features on the table because of the time limit. Like I said, I was shocked at how much content the game had considering the time limit.
Switching restart to the grapple button sounds like a good idea to me. I did forget to mention one minor thing, I think the "Press jump to restart" text would be better in the center of the screen. It's not a big deal since you learn how to restart early on, but there were a few times it took a couple seconds to figure out I was dead because the text was hard to spot.
Thanks again for the game! I'm following you on itch now, so I look forward to any revisions you have as well as your next game!
