Completed the game (I think)
Activated all of the generators and did the final quest. A few complaints:
1) Why have that many spaces for attacks and abilities if you're not going to fill them up? It instilled false hope. Also the reload times for every ability is way too long.
2) After the first area or two, once your pet dies, future pets will *never* be able to catch back up to your level. Every single pet hatches at such a low level that it takes a crapload of grinding just to make it strong enough to help kill anything. By then, you'll be too strong for its contributions to matter.
3) Hatching times are too long. Make them based on number of kills or exp gained (without going to ridiculous numbers) instead of getting up to 3+ hours.
4) Could use more variation in equipment. Light armor that gives less defense but lets you move quicker, heavy armor that adds strength, etc. Also make said equipment medium or rare drops off monsters.
5) Each area should use different music, and perhaps have a boss (related to story progression or just for the sake of side questing) and boss music.
6) *SPOILERS* There was no resolution to the story. You're a castaway on this island, no explanation given as to how you got there. The village leader says he'll try to help you off the island, in the meantime you help the village by activating all the generators. Your reward? "Oh we don't know how to get you off the island, but you can stay as long as you like anyway." Very disappointing. I'm assuming you did this in order to more easily create room for a sequel but it was still a huge letdown.*SPOILERS*
7) The fetch quests are annoying because everything only drops one item at a time and there's no way of controlling which thing will drop next. Sometimes you'll get nothing, sometimes gold, sometimes a fragment, sometimes pet food, and sometimes the item you need to collect. Perhaps increase the drop rates for the corresponding items when you have the quest for it active.
I haven't completed the quest for the ice sword yet so I'm not sure if completing that will unlock new quests or not. However, I don't intend to complete it either because getting the ice shards to drop is an incredible pain in the ass and you need 25 of them. No thanks.
I gave you a 4 because it has great art, a nice concept, and it is addictive (for me anyway), but the flaws outweigh those perks. I would urge you to make a sequel just because I can see you put a lot of effort into this and you'd probably be able to get it right on the second try.
