CrystalsTD by Blist
CrystalsTD is a tower defense game set in a futuristic universe.
Deep inside old planets' crusts lies precious crystals. Your goal is to go down in sublevels mine with a big plateform elevator. Plenty of monsters will attack you, so you have to build towers to defend yourself while the core building gather crystals.
Each floor is harder than the previous, get the deepest as you can !
To build a tower, click on the icon on the bottom of the screen and click on the plateform. To upgrade a building, click on a building and click on upgrade on top left of the screen.
You must protect the Base building:

There is 5 towers :
- Canon tower throw a projectile that explode on touch, affecting all enemies around
- Mini turret fires ammo that directly affect an enemy
- Electric tower fires a strike on an enemy and touch enemy around, creating a chain reaction
- Shredder affect all enemies around the building
- Heal tower repair the tower around. It's an ephemeral building, it loose PVs while repairing.
Kill enemies to get crystals, blob are pretty easy to kill, spider robots will drop more crystals.

Well done, this is awesome!
It would have been nice to see the price of what you were buying before you buy it, but other than that, I thoroughly enjoyed the engaging gameplay.
Keep it up!
Just some minor things I would improve:
- Different colors for enemy health bars and/or shorter health bars. It gets a bit confusing later on.
- Balance. For me it feels like the shredder is just superior to the other towers. And the game felt a too easy in total. combined with the length of the game i lost interest after the first 10 levels.
After all a great game! Well done!
Adding building prices to the main hud could help understanding their cost
The game is quite slow and lengthy, a "fast speed" option could be useful
Graphics is very clean, but I feel like turrets could stand out more
Audio is great, love the soudtrack. Mini turrets sfx can be quite loud and in the front, making it quite annoying after a while. The explosions feels rgeat though !
I had fun, but I don't have the patience to go to level -100 ^^
Tower defences are always great =D
Unfortunately, the game bugged at level 6 for me. No error message. Opponents just stop comming and the game doesn't progress to the next level. Nevertheless a great game!

This bug affects both versions of the game, including the updated one.
