Hello very good game for a solo dev in 10 days, congrats :)
I few things I would improve if the game evolve, give the player the possibility to have a larger view by moving up, or simple change a bit the camera for a more top down view to be able to see more of the map without the need of moving around.
Also I think it would be nice to let the player rotate the connection in any manner they want instead of having it set a position already, for the sniper tower I think this also would be nice to let the player point it wherever they want.
Probably reward the player with more power full weapons or upgrade as the they move up the waves, I felt a bit repetitive after the 10th and not having the feeling of being rewarded enough :)
I got to wave 19th but then the game crashed, took a screen shoot maybe this can help
