I gave it a fair fifteen minutes. I really, really like the concept and I would like to see more. I only offer one suggestion and I hope others try this out and form their additional feedback,
would you consider lowering the initial prices of the turrets? I am unable to make it past day 2.
I can move around and I discovered I can break the walls, which yields more resources than just the crystals, but I like looking for a spot that has all 4 relatively close that be reached with nodes.
it's possible I encountered a bug though. On my first instance everything appeared to function fine. I didn't survive. I had noticed around the 4th iteration, the deploy timer remained at 0 until I manually clicked the button. from there I only had about 5 seconds to start building before being attacked by enemies.
I also think it would be nice if the enemies moved slightly slower, it's possible through testing you as a developer might be used to the mechanics of the game a little more but as a first time player, that's just what I am putting out there.
I also admit I do not know how to use the nodes and buildings themselves. I did discover energy seems to originate from HQ and go to a blue node before the turret building.
could you possibly provide in the reply what the buildings all do?
HQ = defend
walls= re-routes enemies
turrets = shoots enemies but needs to be placed near a node?
extractor = ?
blue node = extends view and range
regen = heals buildings/makes energy?
at any rate, I appreciate the effort you put into your game, I really do like it.
*EDIT*
I scrolled down and seen in your game description some of the information I was asking for. I am not the best reviewer but I genuinely think your game is pretty cool.
