& margin can be remove by adding
cfg.padHorizontal = 0;
cfg.padVertical = 0;
To html/src/.../HtmlLauncher.java in getConfig()
Thanks so much for the advice! I made those changes, it seems like the recompile button is gone. The padding is also gone. Sorry I didn't really look into this before because mine was a last minute submission. Anyway, is there a judging or voting period in this jam? Because if that's the case, I can't add the updated files before that period. Otherwise, I'll add the changes right away.
Again, thanks so much!
Edit: I also added some background music and sfx for the bullet.
