Hm, I also wanted to suggest some stuffs :
PLEASE add another type of core like a bigger and stronger one. Nuceus is not enough for long missions and putting on vaults will take some room y'know
CAN you guys make like the core itself has its own installed turret. Really I want this.
MAYBE you guys can add a mod maker app for Mindustry? Making mods manually is quite hard actually. Especially making lots of sprites and buildings.
PLEASE add more mech pads tho, like a builder pad or destroyer, you know, each type?
KEEP the feature that players are allowed to control produced units, I really like it.
HOW about units that can only go on waters? Yeah I know its already on the v6 alpha but its quite glitchy.
MOTHERSHIPS. Like a unit that launces smaller units. For exam : Revenants launces a Wraith Fighter every 50 seconds and has a maximum unit of 2, that would be great.
IF theres a Meltdown, it will be good if there are also a Freezedown, a version of Meltdoen that freezes enemies instead of setting them on fire.
Thats all I can think so far, hopefully these can improve the game for good.
