I found the borrowing from Zelda (Sounds, Fonts) to be more concerning than the Pokemon similarities. Like you mentioned, there are a ton of capture game clones that are similar. The Zelda lifts are the area where I feel they may be flying too close to the sun. Either way, the game has a fun loop and I'm not a Pokemon player more of a survival games enthusiast. Been a good time with friends I hope they are able to navigate the IP issues.
