1. It is designed as a desktop game. There are few input events, and what is there is bundled together, so you can probably add touch controls in like half an hour. Also, it can be tricky to bring this to mobile devices considering the fixed-size rooms and map tiles. Honestly I have never seen a metroidvania like this on mobiles.
2. Since this gamekit is modeled after Metroid, there are only ranged attacks. I am open to adding new things if there is enough demand for them though.
