Tbh, very addictive gameplay :)
I think this game has a hight replayability and it has a great potential!
I would however improve a couple of things (just my nitpicks 😁)
- The tower placement is a bit odd - you have to press a button in the left upper corner and you don't have control on where the tower will appear in the game. Sometimes towers were on top of each other and it is hard to pick which one I want to move. Sometimes a tree could spawn on a tower but I don't want to move it so I have to be careful.
- I think would be fun to let player to move towers as many times. That would let you to introduce a mechanic when a player can expand the borders of the kingdom and push wolves miles away. I also noticed that they spawn in a close area around the town only when I was trying to build towers further away on the map.
- Also, nice touch with the leaderboard (though I would add a text field to let player to write its name so the score would be more personal)!
Overall, this game is very fun to play, extremely addictive! Well done and good luck in the jam competition 😉
