It seems like this game isn't for you. But I can assure you it's not that hard.
The cyclops have, what? 3 attacks if I'm not mistaken:
- one swing to the side that they can continue up to three attacks
- one straight attack when they jump at you and attack you with their two arms at the same time
- another straight attack when they jump ON you (good opportunity to attack their eye if they miss)
The way that I defeat them is to come close enough to let them do a swing, wait a little to be sure that they won't do a combo and hit. Rinse and repeat. Sometime, they do the jump attack but it's not different. Stay close, but not too much, wait, when they attack, do a back dodge, then go in and attack. And when you're good enough, you can even stay close to them and dodge to the side when they do their swing attack (but in the right direction, if the attack comes from the right, dodge to the right).
And for the boss, be sure to have the "needles thing" that cures you from paralysis. You can find some in a cave to the left, just before the last barrier and the last straight road to the boss.
And you can also use a cup thing to summon someone.
