Thanks so much Jack! I’m delighted to hear you’re enjoying the game! :)
Using lives as a resource to save ammo is a really solid strategy as running out of ammo is basically a death sentence, especially in the later levels!
As you push into levels 3 and 4, the level layouts become more claustrophobic so quick decisions and solid routing becomes even more important
I spent a lot of time polishing everything up, so I'm really glad it shows!
