Love alpha client was available for download, so you can run the engine on your system and help the one-man-developer, Eskil Steenberg, with gathering data for his server. Eskil has gotten done that portion, however, and has now opened the anticipated game for alpha testing audiences.
Eskil has stressed on his website that much of what Love is now may not be what the game is in a few months or years, and that alpha will be chock full 'o bugs. Things may have been going really well for him, but he is giving no one any assurances on how well the alpha will function.
For those interested in Eskil's project, the open alpha will cost you 3 Euros (about $4.50) so Eskil can pay for the servers and bandwidth. Eskil has also posted the full information on what the account creation page does, which can be found in the middle of his information on Love's alpha test.
