Even though the game is timed manually, I paused after killing the last boss (not necessary if you plan on doing a run of this game). The time is 2:01:39.
I would recommend skipping the card collecting sections, they take a while (but at least they help provide extra experience, as well as the cards).
When I get to the second earth demon, skip ahead 6:20 (I get extra potions during that time too, but only to refill to fight the demon more).
Skip ahead the slime and ax armor part 5:10. Then when I'm at the ax armor in a different spot (because I didn't get his card the first time) skip 2:40.
I somehow got the golem card from an electric skeleton, a card I don't use.
The heat shade only took a minute, which is pretty lucky.
The last card is from the were-panther, which takes 5:50. This part has taken me more than 30 minutes before, several times, so I got lucky here.
Card magic I used were the fire whip; ice whip (for the brain floats); venus + salamander and venus + serpent for the +25% attack and defense respectively; venus + mandragora for +25% luck for card hunting; venus + thunderbird for magic that basically more than doubles your attack power; jupiter + serpent for the 4 ice balls; jupiter + thunderbird for double defense.
