Thank you for the feedback! I agree with all of them ;p
The map was a late post-release addition, literally the definition of an afterthought. But now I have a base to improve in subsequent games. (Though making more detailed shapes is technically tricky and I haven't figured it out yet...)
Combat has never been my forte, even in 2D, and that's something I was dreading in 3D. Likewise, I expect to build upon this in the next attempts.
But fear not, while I expect my next game to be similar to this one (probably a sequel), I definitely plan to make more 2D games in the future! Though my first priority after this will be the Silent Paradise Anthology Steam release, so it may take a while ;)
