On the plus side: Get both perspectives :P
Negative: Mostly that the boats movement makes it more difficult in an annoying way and that it's pretty much same old.
The only problem I experience is quite some lag at quite a few positions of the map. It's not the regular "mac-lag" I experience and just putting it out there if more people have the same trouble.
To LightYin and other people having trouble with last level brilliant. My tip is to focus on few tower at the beginning of the level (e.g. 2xChill + 2xBallista on each end) and preferably two Evileye close to jewel den for the early waves and ninjas low on health. Just focus on the towers at the beginning and make sure you conserve as much mana as possible, spending it only on ninjas when necessary. It's still a bit random whether your mana will be sufficient or not I'm afraid but with most Undead skills maxed out and some point Orcs and Demons it will maximize your chances.
Sidenote: I think the level pack felt a bit too easy but that might on the other hand be because the game is less random with skill alteration etc. from the original game (which is much appreciated! :)
Just don't press the jump button and he wont double-jump. I'd say the "random jumping" is a good thing, otherwise the little monocle-dude wouldn't be able to jump in time when really needed.
Cute game, like the brain-ache it causes :) I'm missing a marker for the tiles you know you have to keep free. Like the flag in mine-sweeper you never use.!
