Hi! Thanks for reaching out. It's cool to see someone else was inspired by the same Armor of God video.
My goal was mainly to recreate the original video's game concept as closely as I could. I spent a lot of time trying to match the original sprites, which it became evident not all were 100% square and exactly replicatable.
Sometimes it was difficult to resist adding levels or extra gameplay features, but striving to keep things as they were in the video helped me limit my natural tendency for scope creep. I focused on embellishing the stuff the video didn't show, like what happens if you bump the back of an arrow, or allow the player to not constantly walk right. I must have watched the original hundreds of times by the time I was done.
Near the end of development I got in touch with the video's creator, who gave permission to post the project and shared some of the original music and sound assets.
I checked out your version too. It's fun to see the same video taken in a different direction. Thanks for sharing it!
Your missionary game looks cool! I need to try it with a controller, my thumbs don't cooperate with screen controls.
