Yeah, I don't recommend the web version, but provide it as an option for convenience, as its scale is smaller and performance isn't as good.
Yes, my feature list includes elements that would transform this into a more traditional roguelike, such as power-ups every so many rounds, etc. However, time was limited, so we will see where it goes after the jam.
Adding user indicator for when you are pointing at the dead zone is another feature I have on my list that didn't make the cut. However, it is one I may try to get into the game if I can find time tonight or early tomorrow.
I already have a user indicator when the ship cannot shoot because it gets hit by a pulse that disables its weapon. This is an enemy that has a slight chance of appearing later, after wave 5, I think. However, I don't think it would work for pointing at the dead zone, but I have been noodling on it for days.
Thanks for playing and providing feedback. I hope to keep working on it after the jam.
