Just finished a few games, and I have some suggestions.
The first suggestion is based on the 25 pain and 50 damage Ms do, and the fact that I wouldn't touch on with a non-projectile.
So are you planning on making projectiles randomly appear/dropped by enemies soon? Because even if I only use them on Ms, I still run out rather quickly.
None of the enemies have ranged attacks, meaning even Ms would be a laughing stock with projectiles being spawned. Maybe you should implement these at the same time.
Give a bit more cover (maybe some doors), so you can use tactics to evade enemies more easily.
Beasts are a joke. When fighting them one at a time (which is usually the case as I try to make sure I only fight one at a time) you take no damage except in the rarest of cases, as you usually kill 1 hit, and they usually miss.
Will the game always be played like this, rather than a normal roguelike? Not that that's a bad thing, as it's quite short and fun.
The aiming system needs the *s between you and the X, I need them! D:
