Happy that you like the amount of heart drops; I had actually planned to change it and just kind of never did because more important things had to get done, and, well, at least the heart drops worked, haha. Hearts will probably be just a little more rare in the post-jam update.
Yeah, I've noticed and I've gotten a few other comments about lag, especially with the fire wand, and (for reasons I still can't quite figure) in the sewer. Hoping to get most of that smoothed over.
And the knockback! Totally agree! Woo buddy, it needs work! Probably the worst feeling part of the game in my opinion. It's already been changed a bit, so hopefully it will feel better once I upload the new build after the jam.
Thanks so much for taking the time to play and leave some feedback!
