Warning Forever is a fixed shoot em 'up with a simple 2D graphic section and vertical scrolling. It is from the Boss Rush sub-genre; that is, there are no common enemies or previous levels to pass, there are only bosses in each stage which must be destroyed one by one.Apart from that, there are no bombs, the player has a defined time limit and the system subtracts 20 seconds from the counter for each death of the ship; which makes it certainly very difficult.It was coded by independent developer: Hikoza T. Ohkubo (Hikware) and has always been freeware since its release in 2003 for Windows.It is considered a classic within the Doujin Software and can still be downloaded from the Hikware web-site.In this sample, I play and pass the first 4 bosses of Warning Forever (version 1.08) and here below I leave the link to download it for free:Link to download free Warning Forever: http://www.hikware.com/Prod/index.html#wfThanks for watching the video.
