Damn, I think I faced a bug very close to the end, I've got plenty of keys, several moves, like 10 Repair kits and 5 Energy kits, now what happened is that first I could not target one from the 3 enemies of the room with my moves, then now I can walk like I'm not in combat while the enemies are still there in the room and the doors are closed. I might not immediately restart, I think I've seen about the full game.
There might be another bug, from one point I kept regaining my energy during fights when performing my moves, the enemies actually never got to play, I could infinitely play until they were all dead (although with the flamethrower and several energy kits they may have not played a lot).
Past these, the game is pretty good. Movement is perfect, the view is ok although I prefer to see the tile to my left and right, the combat system is good, there's plenty of resource management as well as looking for extra moves, there are also plenty of ways to reach the different parts inside the dungeon, including ones you don't want to immediately take or you'll get destroyed. As a result the dungeon of this game stands out.
Very good game, I had a lot of fun with it.
