I've been working on a mobile game, and in the game the player can choose between different bullet types or power ups to destroy enemies. The game can get rather fast paced, and I've been advised that my current system of weapon selection (you only have to watch that video for a few seconds) is rather tedious. It's been suggested that I choose a faster/better method. I chose my current method after taking inspiration from Witcher 3 for PS4 (the interface for choosing spells in Witcher 3 is really good), but perhaps I didn't implement it as well. I'm not sure about adding a sidebar because it'll take up valuable screen real estate, especially since I'll eventually remove the "restart" button and make room for a pause button and score display. What selection interface do you think could work? PS: If you don't have any suggestions, you can show me a game that has an interesting mechanic that could help me.
