Major bug: if you leave the screen without picking up the heartstone piece, it is gone forever as the monster with it will not respawn, even if the quest is abandoned and restarted.
Wow why do the lasers have to generate smoke every time they hit something? They generate enough lag that I can watch the hundredths of seconds count up when they fire when you have a lot of turtles and lasers.
There are so many spelling errors in this game it's ridiculous. Examples: klicking, pionts, bunus, and others I can't remember. It is a bit unpolished and simply using a spell checker would pick the typos up. Also, for quests, it would be nice to have some way of seeing what quests were accepted and from where.
Why is it that adding normal zombies to my army makes my army worse? It's not just an averaging thing either. I have better success with smaller armies that don't include basic zombies than if I fill up the remaining spots with basic zombies. That doesn't even make sense!
There is a huge flaw with the living heart. If you sit in the middle of the screen above a laser and below the blue bullet, you will never be hit and you don't have to move. From this position you are also able to hit the boss continuously. Please fix this! Otherwise it is a really great game and I look forward to a sequel.
Customer wants something I don't have... Offer something else that is similar. "What kind of service is this!" Excuse me? I think that is nicer than telling them no, which they seem to receive more politely.
Good trick for fighting the boss: If you are having trouble dodging his attacks or getting him to hit himself, dash into a wall. You won't take damage but you will be stunned and temporarily invulnerable as though you had. This will allow you to heal or get the boss to chase you into the boulders safely.
You can drop any unneeded items you are carrying. Just click on them and in the top left corner of the item box you should see a red circle with a line through it. If you click this it will ask if you want to drop the item. This lets you get rid of useless items like crumpled notes.
Why oh why do I have to press a to pick things up? That also happens to be the button to go into buildings. It also happens that when I pick up an item next to a building I also go into that building. This gets quite annoying. Also I seem to have a nasty habit of teleporting into walls and having to go back to my house to start the dungeon over. It is a very fun game, but bugs like this make it annoying at times.
