I can remember the game clearly, it’s a lane based tug of war style game where you send knights and archers down your side and the enemy does the same but with goblins/orks. It has a cartoonish art style, similar to that of castle crashers and as the levels progress, the goblins change colour as they get harder and you can upgrade your troops and unlock new units and things. I hope thats enough information for someone to find the game for me and it would be much appreciated.
Thank You!!!
I didn’t find the right solution from the Internet.
