Simple, but felt fairly solid. The different enemy types and barricade types offered some welcome gameplay variation.
I found myself wishing that I had strategic opportunities to shoot enemies without consistently making myself vulnerable. The final level ended up being the most enjoyable for me because I was able to approach it that way.
That said, I did have some fun lining up the tanks to shoot one another, though, and I loved the spinny victory animation!
Hope you had a positive experience with Godot, and thanks for doing Linux builds. Always nice to see sources too!
