The story needs some improvements, but all in all good game. Some goldies are quite difficult, I like the additional challenge after the story.
How many levels can be completed with platinum, I'm pretty sure there are quite a few, but I didn't figure out all of them.
Really nice game, but the upgrade system is really annoying. It takes like ages to place a lvl5 tower with 3 gems. I would like to add purchased gems directly to the tower selected. I don't see why i should buy one and not directly use it. The deselect after upgrades is awful too. Just a suggestion for a sequel, cause I hope there'll be one.
Btw the relevance of skill points is too significant for me, the difference between almost golden and complete failure lies often in a lack of some skill points. Thanks to the valentine glitch no problem if you really want he badge.
I hate walkthroughs. Everytime I play a game with a wt i don't think myself. If I can't figure out the solution after 2 views, I look at the wt though I hate it.
