Will further check. Did you see the comments on indieretronews.com ?
I'm just browsing. Overall Ami-H.E.R.O. It was created because I wanted to see if I could faithfully reproduce flying up, falling, gravity and collisions on the tiles of the room. Once I got the hang of it, I decided to make simple graphics, the first level and simple enemies, similar to those in the original. It is not a faithful copy of the game, but only a model based on the original. There are some shortcomings, e.g. collisions when shooting, but overall I think the game is playable and addictive. If I have enough patience and a graphic designer is found, the project will continue.
