Hey! Thank you for the compliments and the feedback!
It's a shame about the viewport issue- I just found out yesterday that can happen, and I suspect it's a Mac issue, which I wasn't able to test due to not actually owning one (and also, not really thinking that the browser version would differ in such a way based on OS). Would you mind letting me know what OS and browser you played on?
I also wonder if part of the difficulty in seeing enemies is due to that bug- if it was working properly, you'd only see the section of the screen that has the background, which would fill up the entire 800 x 720 viewport. That said, I do think enemy clarity is something I could work on regardless.
As for the difficulty, I definitely wish I would have made a more accessible game for the purposes of this Jam! I think that was partially informed by using Castlevania as inspiration. You live and you learn I guess!
Anyway, thanks again for playing and for your thoughtful comment! :)
