Crystal Planet

good concept, but needs work.
I'd like a mute button, as the music DOES get on your nerves after a while.
Also the difficulty ramp needs work, as you cant build/upgrade turrets fast enough, and after level 3-4 any mercenaries you hire dont live long enough to actually DO anything.

Really hard game. Mercennaries are completely useless, they can't even kill anything on the first day and die way too fast. Armory serve no purpose, they produce a medkit the first day, then nothing else. The money is too scarce too, especially when combined to mercennaries who cost 10, and die in one or two hit from anything. Only reliable way to " play " with how durable ennemies are ( and how inefficient/costly any defense you build is ) is to make turret in a narrow corridor, with one/two doors and the crystal chest behind. It's the only way to actually kill anything, building a maze is not possible ( too costly ).

Nice game, but a bit difficult at the beginning. my only solution to win was massive turret spam together with doors in a long open corridor with doors at te back end. If completed the game is more than boring because the enemies dont have even the chance of damaging the doors. I played now for 30 minutes and on one cmae through. Nevertheless i like your work and there might be a lot of potential in it.

There is a bug where if you have nothing in your crystal box they will still "steal" them and reward you "ghost crystals" for killing them. probably unintended but i like the idea of more risk=more rewards. but... as many others have said the enemies scalate too fast. Drones and mercenaries are way too weak (or too expensive). some suggestions include: add a Healing station so your mercenaries dont die too quickly OR heal mercenaries after each wave AND allow to keep powerups sorted (maybe with hotkeys) instead of droped on the floor AND allow us to open/close doors (so we can do some flood control). Hope this is enough feedback. cheers~

A few of the buildings are a bit glitched, like the armory, which doesn't seem to produce anything in upgraded form. Other than that, I'd add a line of sight check to the guns so that they don't attempt to shoot through solid rock.
