Hello!
I agree that it can feel punishing. I had some trouble balancing this game for sure! I included health pickups if you have trouble but they drop randomly so I understand it could be really difficult for some players...
As for the input and audio lag issues with the web build - yeah I agree that it can cause issues. The system I'm using specifically accounts for it, however... so it shouldn't be an issue more than it would be in any other game that uses timing.
As for the visual art - I'm normally a pixel artist, this artstyle is completely new for me. I wanted to try something new, and I agree that it could've looked a lot better.
Thank you for your review!
