That said, it was more low stress fun than I've had in a while. I find myself playing games for stress relief, and I have a tendency to play on the harder levels so it stops being "fun" after a while. I was playing metro 2033 recently, and while a nice game/story I don't really enjoy it that much because the sudden appearance of fast moving monsters that are hard to kill with limited ammo is just to much. I guess I should drop the difficulty but that seems like cheating. Games like that should have a better sliding scale for how well your playing and adjust so the player doesn't have to reload 10 times...
Also, was pleasantly surprised to see the roguelike is played in the browser. Rot.js looks awesome.
The "attack" will be one of four choices: You attack, you attack with magic, the enemy attacks you, the enemy attacks you with magic.
So the optimal solution is: Maximize the attacks that benefit you while also picking attacks that either lessen the damage you take OR choose damage against you that set you up for bigger patterns on the next turns.
edit: looks like is can get deeper too. For example, bats have no mana and cannot attack with magic so it is a nice way to move some blocks without taking damage if you dont have any moves.
