Hey, just played it. It took 12 seconds to go from pressing Launch in the itch.io app to the main menu appearing. Pressing play took me to the game instantly. My computer is not particularly high-spec or anything, so it doesn’t seem too bad. Curious to know what it’s loading, though. :)
I enjoyed slaughtering the evil penguins, but I do wish I could shoot and move, or shoot and rotate. That would have made it a bit easier.
Your world is pretty large, which is cool, but I didn’t have a good idea of where anything might be. I happened upon a couple of buildings, but purely by chance. When you get to the point of adding a helicopter, you might want to give some sort of point to where it is.
Looking forward to coming back to this. Great work so far! :)
