Heya, sorry about the web build - you can zoom out your webpage on itch.io to make the game window fit your screen - on Windows this is done with Ctrl + Minus or Ctrl + Mouse Wheel Down.
I'll look into improving the nuke explosion after the jam period! I wanted to make the bomb break and fragment into different shards, and set all your houses on fire HAHA (crazy ambitious), but given the limited time I had to do my best to balance visuals and gameplay - if you have ideas on how to make the nuke explosion more awesome, please let me know as I will be working on this game post-jam and I'd love to add those in!
Thanks for the feedback! :)
