I'm a big fan of both of those games! While I wouldn't say ZeroRanger was a direct inspiration, it was probably subconsciously factored in. For the text transitions i mostly looked toward Ikaruga's very opaque translation. There's a narrative I swear!!
Ohhh, you know Zero Ranger and Void Stranger, they are really awesome! Ikaruga was also a very innovative game, I’ve always loved Suzuki’s art! I recommend Sin and Punishment, which features the same artist and is also from the company Treasure. Anyway, you’re a great artist!! Greetings and have a great day!!
