Hey Dungeoneers, sorry for being a little quiet here lately!
I’ve just released Shattered Pixel Dungeon v2.4.2, which is mostly focused on followup balance tweaks, but also fixes a few bugs. Here’s a link to the changelog on Steam: https://steamcommunity.com/games/1769170/announcements/detail/4185612701676471088
I’m not familiar with Sandbox Dungeon, but if it isn’t being developed by Evan, shouldn’t you ask the Sandbox dev to optimize it?
