Really well made game. Good job!
Especially considering it's your first published game.
The artstyle is charming and it's satysfying to see all the guys shoot at once.
Some constructive feedback now :)
For some QoL changes I'd like to see laser sigts for the soldiers that stop at whatever would stop the bullet. Especially for the shotgun guys you need to kind of hope that you predict their trajectory right.
Also it would be nice that after failing a level you had the same configuration and only click to change certain soldiers. Combined with above point, it's a bit tedious to place 8 soldiers the same way as you just did just to change the position of that shotgun guy who shot different that you thought.
