“The game is great, but I want more content updates”
“It feels like the game is finished too quickly for a roguelike. I’d love to see a new update or DLC with a new location (like a different part of the flooded planet)”
“Devs, please update the mobile version! I really want to play with the new graphics on my phone when I don't have access to my PC!!”

“definitely should've just added multiplayer to this base game instead of making it separate. I get that one is more tower-defense but I like to control the mech fully.”
