very nice game. done on first try... and i am not very good at these games, therefore i believe it's a little to easy. but maybe for that very reason, i liked it very much :D
for the devel:
the buy health button is broken (buying health during the game does not charge me anything - free);
tips for players: invest in health and damage. at the higher levels there are so many enemies that speed is futile :P.
and the 6'th challenge is a great money maker (4 min with the most money yielding enemy :D:D:D )
even if it's the same concept used over and over again, i haven't seen henchman AI this good. these were really useful, not just lowering random enemy HP.
for the Den of terror campaign, you need to collect all the 9 shards of... the thing that you loot from ... fearsowers (i think that's there name... the guys that look like the badge icon:P ). when you have 9, you can teleport to the boss. that is why you can go for 9 levels (if you collect them from each one) or more levels if you do not kill each of the fearsowers.
how can you visit the shop? except with the scroll... i had one, used it, thought that i would be able to buy a new one from the shop... seems like i cannot.... so... any other ways to visit the shop ?
