It's interesting, but it needs more depth. I'd like to see more level elements instead of just corridors and open spaces. The combat is a bit bland and I was at almost full health until level 8, where it just gets hectic. You seem to auto-aim to the nearest enemy, which is strange. Also, at one point the sound just stopped at a point where I picked up an invisibility cloak. And I often come to doors that let you skip floors and it says I need more small keys when I have some. Do they take 5 or something?
it's a first "onegameamonth" release, as explained on the site and the readme, etc
more stuff is gonna be added like quests, etc.
auto-aim is there cause the game is originally being designed for mobile devices.
the doors with higher numbers require more keys, if you are in dungeon 3 and a door says 5, it needs 2 keys, etc.
