bankl function is annoying and should be removed, so that interest is earned on money you have and not just deposited money. The bank is simply unneeded micromanagement.
Before you complain about the game being easy, consider if it has to be difficult. That is not necessarily the purpose.
I find it beautifull, relaxing and good. I also find it easy, but so is a bunch of other good coffeebreakgames. Thats part of the concept.
The faster and more efficient I get through a battle, the less point I earn, thats pretty bad. Sitting there trying not to win, will earn points and exp.
the chessgame is difficult or bugged. I placed the pieces, and moving a piece to f-5 his simply making a mistake. That's all.
Name of the piece is no good either.
I think this game has the material for something great.
The idea of having your own cards instead of using the same ones as in puzzle quest is good.
Work on it, and give us more interesting quest for the (almost) promissed sequel.
I'm looking forward to it.
One thing I would like you to chance though, is in the traveling. When traveling through several sections of green roads, i would be nice to be able to simply go all the way in one click instead of visiting every village along the road.
i agree with those who say the game is too easy. Could be changed I'm sure. The real problem however is that there is too little evolution in the game. Nothing new happens after a few waves. Try creating some new enemies and some bosses. I know it is ordinary, but that is what we want.
Another thing might be to add specialization. This could be done, by linking upgrades, so that upgrading your armor, would also raise the prize for tracks, due to higher weigth and such things.
Overall, you are on your way, but still some work to do.
Keep it up.
