How to beat the 10 candy arcade game ("Super RPG")?

I can repeatedly get to the dragon, just to fail there with this strategy:

Be warned, the monsters have randomized stats. This strategy can randomly fail you. (+ means and)

0: Wooden sword
1: Copper Shield
2: Iron Sword (pot if below or at 4 HP)
3: Health pot + Silver shield to 9 HP min
4: pot +15 maxHP
5: Diamond Sword + pot + 20 maxHP
6: pot to nearlyfull (meaning don't waste money) , 35-40 maxHP
7: Shield of El Cid + Pot, 35 HP necessary.
8: pot to nearly full, 60-65 maxHP
9: pot to nearly full
10:Vorpal Sword + pots (Vorpal is necessary for floor 12's bombs)
11: pots
12: Morgul-Blade, Ancile, rest in maxHP
13: Pray you get three chests, into maxHP
14: No strategy yet past this.

You can probably skip the Excalibur. And the Aegis?

Past fourteen, the monsters get insanely strong (floor 21 monsters have 94 ATK), and ATK equipment starts costing 1k, 1,5k and 2k, DEF equipment stagnates at the Aegis, while they just drop a few hundred total at best. Not sure if this can be beaten. I got 40k candies for beating the dragon.

I got to floor 22 using the guide. You can skip excalibur and the aegis. Aegis only gives you 2 more def. Problem is I never saw a better shield than the Aegis. Eventually you'll get mjolnir as a weapon option (2k). I didnt get a chance to grab it because I was an idiot and bought excalibur after I'd passed it up 3 or 4 times. I basically just funneled money in to max hp (got up to around 470).

got 40k candies as a reward.

It's kind of easy to go up to lvl 13 but I've found no way around him so far. Prolly need a lot of boxes and luck.

For early levels try shield>sword>sword>shield+pendant Make sure you have the 100 coin sword and 25 hp by level 7
