Thanks a lot! I had to find time time to make a tutorial introduction, since it's not super straightforward, ahaha.
The timer is 1 extra second long when you reach zero, so the feeling of doing it barely is also due to this trick. I'm glad it works! XD
Also, I love giving stories to my characters. Sometimes I make them cameo on main games.
I was planning to add the explosion preview during placing, since that part is supposed to be full puzzle. But also to see the range of the flames before the countdown begins.
