About
"This fortress is our home. We will not let the enemy shatter it."
— Captain Phoebe of the Crystal Guard
You take control of Phoebe - fierce warrior, skilled archer, resourceful engineer and fearless commander of the Crystal Guard. Summon powerful soldiers and snipers, mount defensive turrets on the battlefield and get to the frontlines — whatever it takes to leave the fortress intact.
Units recover a limited number of action points (APs) per turn, requiring careful planning. Should you act aggressively with your current points to approach and attack the enemy, or stay put and defend to recover additional points while letting them get closer to the fortress? But beware: enemy units can act the same way!
In this game, you only control the main character. After you make your move with Phoebe, all ally units take their action simultaneously, followed by all enemy units at once, resulting in a very fluid and quick passage of turns!
Spend your gold between battles to power-up each of your units, increasing their Max HP, Max AP and AP Recovery, Damage, among others. Be prepared, for the enemy waves will grow relentlessly.

Experience stage progression divided into chapters, providing different environments to play as the Crystal Guard shifts their defensive efforts to each of the four gates.

Jogo muito bom, bem estratégico, fiquei até triste quando acabei ele, fiquei querendo mais kkkkkkkk
Great game for its price point. There are 4 chapters of 5 levels each, and in total it should take about 3 hours to complete. Some levels can be challenging but you can use upgrades to tailor the difficulty to your taste. You can also use upgrades to make different builds viable, which adds variety. The gameplay loop is easy to understand and you jump right into it with no time wasted, which I appreciate. The achievement system is also nice and it adds a few more reasons to replay some levels. I recommend this game if you want to have a chill time for a couple of hours.
I had a great time playing this game. You can finish it in 2 hours and it has enough content for its price point. I love the vibe and the music. I like how the game lets me strategize in my own way and gives me new challenges and villains to fight.
Great game, especially for its price tag Guaranteed to get you a couple hours of fun, could've had a little more units and enemies, but hey, it's only 5 bucks
It's a very simple defend the castle game but quite enjoyable. It's not very long and there's not a lot of replayability to it so don't expect to waste more than 2 to 3 hours on it.
It was worth $5 to me. I enjoyed it and finished in under three hours.
As a old-timer gamer, I do enjoy from time to time a simple 2D good tower defense game. The kicker? It has some sophistication on it's combat structure that I couldn't see back then. A simple, fun and honest indie game. For it's price it is a steal. TIP: Action Points from Phoebe = CASH, make her raise that sword up and let the team do the dirty work.
O tower defense mais original que ja joguei, utilizando mecânicas de RPG. A arte e a trilha sonora são muito agradáveis. A progressão é intuitiva, mas muito bem feita. Dá pra zerar em torno de 3 horas, mas dá aquela vontade de poder jogar mais hahaha. Recomendo!
Little tower defence/turn based strategy. Liked it a lot!
Is that a tower defense game? Is it a turn-based tactics game? Or just a simplistic mix between those two genres? Yep, "Crystal Fortress" is a mix. Not a bad one, even if a bit too simple - technically speaking, you have only your hero, two types of units and one tower in your arsenal. Strangely enough, you don't need much more to stop the enemy waves, and the game is fun without being too easy/hard. So yeah, give it a try, i have played and reviewed way worse TD games :) Gameplay video: https://youtu.be/SOUus38BzGE
