Woah wasn't expecting such a quick response from people.
Glad the idea is liked being that it's so simple I thought it was going to go unnoticed.

Basically the door is just an object that disappears when you touch it and re-appears when you get off of it as long as there are no enemies on top of the tile.

Yea I've got to work on a wave system to give the player a bit of building time.
It's fun to have to build on the go, but you can't always build when enemies are covering up an area.

Thanks! I'm trying to keep it super simple, but I do have an idea to allow upgrading of the players weapon and build items.

Ilu too <3

I was considering going down in size, but I didn't like it when I did.
I find 32x32 to be easier to manage, smaller blocks would just let the player create layers of walls around his base.
You already can't build if an enemy is in the tile so that makes it hard to place blocks on the go.
You can also right-click to salvage tiles for like 25% of their value.
I've now made it so the room is infinite, you can move anywhere now.
