Glad you liked the game, and the character roster ^^ which i'm always a bit nervous about cause i always have this aprehention that people are not gonna like my designs, though i have been lucky to be wrong so far :p
Haha well i'm not sure if they have something special about the way they turn but i'm glad you like this as well :p
Yeah the biggest issue i've seen so far, and i totally agree with that, the lack of any kind of indication for objectives, which i feel may have understandably discouraged some people when level 2 jumps from 5 to 18, but mostly since my wonky system counts per building and thus doesn't reflect that they are just lumped together in just 3 different areas :/
Also yep the mortar is definitively underpowered, and the vulkan ultra OP (at the moment it's almost a speedrun weapon as it can melt most things in seconds) but also some of the structures have too much HP for just static buildings. I have been already tweaking some things a bit, but just didn't publish anything yet cause i don't know if the jam allows any updates to non game breaking issues during the judging period, so i'll see whenever i can push anything.
Thanks for playing and your feedback :)
