Not bad!
I did enjoy this game a good deal... But there were several things that really bothered me.
The first thing was the fact that you lost all your potions when you saved and came back. That's irritating. Not really major, but still.
It would have been more major if I could have picked up more than 10 potions. What the heck? If we're supposed to be limited to 10, fine, but don't TAKE one of the potions I already have!!! I.E. I walk over what would be my 11th potion - instead of going up to 11, my potions go DOWN to 9! Further, the potions that you can't take shouldn't vanish from the ground.
Also with 10... When I reached level 10 my level disappeared. I was still 10, but it just said "Level " at the top - it was blank. What's with the number ten here?
I thought there should have been some type of guidance... I ended up exploring an island with a bunch of level 4 critters before islands with nothing but 1's and 2's. Also, making players just kinda go out into the ocean to find new islands was iffy. I didn't particularly care for it, then got the Golden Pan Flute, so that fixed that problem.
Also, some of those levels are misleading... If I'm level 9, and I fight a level 4 lizard-man, I should STOMP him. Instead he eats 10 of my health, with the 'magic armor' and helmet equipped.... Come on! Get two or three of them in a cramped space and you get owned. It really made my day to be level 16+ and get hit for 30 by a level 4 monster... D:
The boomerang is.... unbalanced. It did cost 3k, but jeez. It's like the 'ultimate super slayer boomerang of doom'. If you wanted to crash your browser, you could have a ton of boomerangs following you - see a monster, run around him real quick and BAM, 10 very unhappy boomerangs hit him at once! INSTANT DEATH. I had a small army of boomerangs following me one time, which was kinda fun.
I really liked the quest items, though :) They were pretty cool. I was walking crazy fast by the end of all that - along with the trail of boomerangs, any monster in the open was basically pummeled while I ran circles around them. I enjoyed the little quotes that came with each item.... I really liked the one with Skull of Dante. Ironic I suppose. Couple of things here: The Ring of Regeneration worked even when I was running around. I don't know if you meant it to, but a health potion will counteract the Voodoo item.
I know this wasn't a big project, but it would be cool to show different armor / helmets... If you're going to expand, please do that <3
Also, it would have been useful to be able to scroll the map when it was pulled up... In case you wanted to find a particular merchant again, for example. (Also related... Does the Candle actually do anything? I mean, of course you can see the items AFTER you kill the monster... It didn't seem to show me beforehand.)
I didn't really like the attack method.... If you missed the monster and clicked next to it, you would run towards it, which generally resulted in a hit. Also, having a way to change the key bindings would have been nice. Arrow keys + mouse = :( . I'd rather use WASD if I need the mouse.
Okay... Yeah, it's time to stop. Sorry for the rambling, but that's my take. Thanks for a good few hours of fun :)
P.S. That ending was ...... Very, very wrong. Hours of searching strings of tiny islands for that?? But unexpected, I suppose :P ( I feel a little cheated, lol.)
