I remember enjoying it a lot right after it was released, I got it during the free month it was on PSN. I then played until the dread shores expansion, but started to get bored by the same-ness of the bases and the lack of encouragement in creativity in making them, because of the danger people would abuse the tools, which I understand.
I tried to make my base easy or medium, using most of the traps to coral players towards what I thought was a fun path, but having to do that meant it looked hard, but it actually wasn't.
(For example, covering the floor you came in on with lava cubes that activate after the Genmat is grabbed to encourage them to keep moving forward and leave out a different way than they came in, standard level design for other games. But that meant it looked super hard from the level select screen when it actually wasn't. If anything, the path forward was too easy. Lots of players just chose to try to hookshot the way back that they came in. I covered that with more traps to discourage it, making the path forward even easier because I didn't have enough resources for it lol.)
I did loving watching people play my bases, even though I didn't have the time or skill to raid the more kill box levels.
So, any improvements since then?
