The graphics are nice. The gameplay is addictive, I couldn't stop myself playing and had to finish it! I don't think there was an actual ending but after 30 mins or so and with everything fully upgraded I couldn't afford enough guys in a turn to overwhelm the goblins so they slowly got less and less. I like how there is a buying phase and battle phase and it feels nice to watch the camera transition to the battlefield at the end of each turn. nice job!

Cool game

The difficulty curve felt sort of "sudden"- one moment barely any of my soldiers were getting killed, the next round they all got killed! I really enjoyed this game overall though, the graphics are great, the different things you can buy and how they interact with eachother are great- I'd love to see this with more balancing, it'd be a perfect game then!
Edit: Wanted to mention, I also had a small bug where I was clicking on the purchase button for the upgrades but they wouldn't buy unless I spammed the button, even if I had enough money?
