Just noticed this game which has development credited to a company I've never seen before (有限会社クラフトマン -- presumably "Craftman" or "Craftsman"). The director is Takuhiro? Kosakaya (小坂谷卓宏), who apparently was connected to Bit2 -- he's listed as representing the company for an MSX magazine back in 1991. One of the artists is Kenji Noguchi (野口賢次) who worked on Shoot Range. --Dimitri (talk) 04:23, 7 February 2018 (UTC)
Seems like they may have been connected to eroge publisher "Wendy Magazine". A bunch of those "games" are tagged Bit2 on Nico Douga, and both companies were located in Sendagaya, Shibuya. PC versions of Chikudenya Toubee were also published by Wendy Magazine while the PC Engine version has a Bit2 copyright, though I'm not sure if they were actually the same company.
Judging from that Famicle Parodic box, they also at one point had a distribution arm (ビッツー販売株式会社) based in Kandasakuma-cho, Chiyoda.
