I don't think I agree.
At least, not until you've got better weaponry and spells or whatever.
I'm only just now at that point in game in which skeletons take one hit to kill. Since there are no levels in the game (or am I just missing something?), I have to grind, at the easier stages (or grind and fail at the harder ones) in order to either earn the gold or find the weaponry to improve my offensive/defensive power. I've failed two stages due to lack of time but one time it was because I did not realize that even though the game is paused, the timer still ran (which is bullshit for a local game and you know it).
Sorry, but I play during commercial breaks when I watch TV and just did not see that.
The 2nd time, however, it was with Stage 4 and its painting maze. I'm sure later on I'll memorize the map but this time playing it, I found it very frustrating. And my only spell is a shitty Summon Spirit with Alucard. At least my equipment is the best I can buy so far, but it doesn't help me when I couldn't even reach the upper sections of the stage in time (or at all).
Sounds like you're being too precious with the game. When I first began, I didn't play much single player. I powered up my character through multiplayer. This gives you the ability to make it much farther than you can on your own, and witness enemy and boss patterns for yourself with the safety net of having a team. If I was playing solo, I would play on the hardest chapter available, and power up slowly, even if it meant dying. That's the whole point of keeping items and skills after you die, so you can get farther next time.
The game was just released for PS3. The community is growing with you, take advantage of that and play online. This game is amazing when you tackle it together with a group of people for the first time, especially before everyone knows all the secrets and has all the equipment and abilities. Discovering the game with a team was the best aspect of it for me.
One tip for Chapter 4 that will make it amazingly easy. When you reach the part of the map past the room with those two dog-gorgon like things and the Chupacabra in the middle, you'll come to a ledge with a brown chest on top. Normally, you can't reach it, but if you jump kick off the Imp (or even the Fire Demon in the proceeding hall), voila! You've just reached the most important switch in the entire level (just past the Gurkha Master ahead). This lever activates the elevator. After which point, fall back down the ledge and continue up past the Rifle-ricocheting monsters, and the hall with ghosts, bats and Gurkha, and just beyond the Dullahan, you've reached the boss room (DO NOT jump in the painting just before the boss room. This takes you back all the way to the beginning).
