I thought this was a great game. The grappling hook seemed fine to me, just needed some getting used to. One question though... When is it over? I'm... well, I don't want to spoil the ending. (If this is the ending?)
Oh, also, perhaps instead of having the speed of the hero be determined by the distance between the hero and the cursor, I think it would be better if it were simply centered on the game screen: Center is standing still, farther left is running faster to the left, and farther right is running faster to the right. This, combined with my previous comment, would make it much easier to control where the hero goes, and how quickly he does so.
Instead of having the camera move separate from the hero, I think it would be better if it was fixated with the hero on the left or right side, depending on which way the hero is facing. I've noticed that the camera keeps moving where the game things the hero will go, causing the hero to be outside of the screen where monsters are instantly spawning and attacking the hero, causing him to unnecessarily die if health is low.
Aside from that problem, great game!
Autoclickers are great until you get to Hellstone Lv. 50 and above, at which point, the auto-click is about 5 times more powerful per second than each manual click anyway.
I have played OH-so many games of this type, and while it... WAS enjoyable, the Medium mode should be easier, and the Easy mode should be MUCH easier... I mean, I can't even get passed level 4...
Now I got the sliding on the ground until he stops ending, followed by a "congratulations" and then "you didn't get a new record." Is this the ending I played for? Or did it mess up again?
Great game! But I gave it a 4 out of 5 for putting the link to the other website IN the area where I'm clicking. My game was interrupted about 5 times from accidentally clicking it.
