When I first played I was missing buildings. But those aren't really that useful that fast. I wonder if there's some problem that makes the game harder on certain systems? I'm using Firefox on Windows 10.
If you can get a few tiles and afford enough gold to build the building that gives you more gold, you could try building some buildings and then stalling for a while and hoping you get stronger faster than they do.
The game is still a prototype, so not fully done, but the main idea behind the game is that everytime you play a match, even if you lose, you gain resources based on the score, and use them in your "Camp" (work in progress) to unlock more stuff that helps, bit by bit, your goblins. That would be the meta progress for this roguelite project.
Also, more perks and new goblins will make the game even easier: right now the skill tree is not complete and there are just a few goblins. I've designed a few that stun and tank the human soldiers, but aren't in the game yet (they help a lot). Sorry if the game is still a bit unfair!
