I finally got around to trying the new graphics version of the game. It looks very nice if not small (I'm sure I can adjust the resolution, but just haven't tried yet).
But after 2 games, I couldn't stand playing anymore and went back to ascii because the player and enemy movement are just so slow. While the effect of seeing the player and enemies "slide" from one tile to the next does look nice, it becomes frustrating. It's the same thing that bothers me about Dungeons of Dredmor. Although the walking animations look nice, it gets tiresome having to wait for the player to finish "walking" from point A to point B.
I would love it if there was at least an option to turn off the "walking" animation for DoomRL. I would much rather have the player sprite move instantly from point A to point B. Or obviously by taking instant steps for distances longer than 1 tile. Basically move the same way it does in ascii mode.
I would imagine that the "sliding" would also affect trying to gain the badges that require finishing the game in real time minutes.
