Great game locked behind paywall

This is a great looking tower defense game that can compete with the best of them, but it's presentation leaves me feeling ripped off. More than half of the towers or accessories you can build are locked behind paywalls. Many tower defense games have these "premium" options that can be bought for an advantage, but are not required to make it through the game if you choose not to buy them. This game is different, in that it makes no attempt to separate the paid content from the free. In your toolbar of available towers, a third of them a must be purchased before use. The game repeatedly suggests options for how to effectively defeat multiple enemies, and all of these options must first be bought.

Levels are longer than most other defense games, and it's not uncommon to spend 10 minutes on 20 waves and then see a massive leap in toughness of the enemies on the 21st wave, causing you to miss out on that perfect rating without the paid upgrades. It's worth noting that the prices are quite high for what you actually get. Kingdom Rush is a much better defense game that handles micro transactions much more gracefully.

It's like the designers made a great game, and then picked through every piece of it to see how they could further coerce the player into spending money. In the process, most of the fun was sucked out.

TL;DR: This game makes you feel punished for not spending money on it

Best Tower Defense Game

First thing, people who are saying this game is "too difficult" get out of here, it's a strategy game. Sorry you've been handed 3 stars easily in the past for similar games but this is one that requires way more effort even with the packs.

This is definitely the best tower defense game out there! It's challenging and it took me forever to beat all the levels. Creators of this game if you are reading this-- MAKE MORE LEVELS! Or at least make the levels more challenging (ie more waves, more aliens per wave, or a way to turn off the packages I paid for, etc.) All in all I would most definitely recommend this game!

If you do decide to pay for packs on this game, it's not like the challenge is taken away. I broke down and did and it still took me a long time to beat the levels

Its great but disappoints

So this game is really fun but very difficult to earn coins. If i were to set up towers badly and I kept losing this wave, I might as well start over the whole mission because I'm stuck in an endless loop of losing and I can't do anything about it because my coins are spent. Another thing is that there are towers that would really help me a lot but I must pay for them. The "general" will give me tips on how to beat a wave but those tips involve buying the towers. It also leaves us with less to work with. I hate playing a game with so much potential but only to find it greedy with almost everything it has
