HyperRogue version 3.1 is released!
This version contains many optimizations, which make the animations much smoother. Mostly due to using compiler's optimizations, but also game mechanics and shape drawing routines are optimized.
These optimizations also make an Android port possible.
There are also some bugfixes and minor features ("dead ivy" shows correctly, necromancy bugfix, restarting after finding the Orb of Yendor no longer crashes the game, help fits better on the screen, you can right click the framerate for hints about improving it.
Here are some screenshots from the Android version. As always, have fun!
