Thank you for playing and the feedback! I hope you didn't miss being able to move towers after placing since that can help with the stategic planning.
I wanted to add more tiles like mud (making the enemies slower), along with so much more things to deepen the strategy. Like upgrades, both to the tower and player, climbing enemies, line of sight with some turrets being able to shoot over them, AoE towers... etc. Will probably end up making this a full release in the coming year so will have time to implement such things then!
