Very nice visuals, it’s main reason why I checked this out first and it did not disappoint. I like that you used simple mechanics and managed to make them interesting that kept me hooked for a bit. I was honestly thinking to myself that this could a great full game, with more character abilities, towers, upgrades etc.
Things I did: When I started the game, I tried fighting the guys first, but quickly realized that you need to be super careful with their range. After getting down to 1 HP, I ran around and focused on building towers until the whole field was full. I then proceeded to spam build and realized you can sometimes build things outside of bounds. See screenshot below. Not sure how to trigger this, but it’s a thing lol
