I like collecting games, especially weird and unknown ones. This is a pair of shmups by RS34 which really caught my eye. I'd like to do a proper write up on the games themselves once I've played them, but for now here is a look at the collectors edition.
Illvelo Swamp is Japanese only, but Radirgy Swag is actually localized and available digitally in English and a few other languages if you're interested.
Also "Love-Hate Edition" is a pun on 愛蔵版 ("Aizouban", Collectors Edition) with 蔵 ("zou", storage) replaced with 憎 ("zou", hate).
