Nice Rogue throwback, I've been looking for a game like it, but that makes shooting easier. Bonus points for being open-source. I do like that you provide a termux build, very cool. I'll try and get that running on my android tablet later on.
However playing under Windows, the game suddenly crashed on me after a mouse double-click. There was no game to continue upon restart :( - and no log or any diagnostic info in the game folder.
One convenience I feel is missing is a "rest until healed or an enemy appears" key, to prevent spamming or holding the dot key which is an easy way to die in most roguelikes.
It would also be nice if you could "run until something is found" with the mouse like in Rogue+: https://sourceforge.net/projects/advanced-superturbo-rogue-plus/. Haven't tested yet with my standalone keypad, but if Shift doesn't work, pressing f followed by a direction like in Epyx Rogue would be a nice alternative.
