Unsung Indie Games

What are some of your favorite indie PC games that you feel have gone mostly unnoticed? I feel like I have far too many examples of this to list, but the Captain Forever series by Farbs is perhaps my best example.

Crawl, Shoot First and SF IV - Bootleg Edition.

Clicked on the link for Captain Forever and lost 2 hours. 

I feel that a lot of English-translated doujinsoft (Japanese indie games) tend to get overlooked. Here's some of my lesser-known favorites; the non-free ones all have demos if you want to try them out:
- Parameters - A JRPG without the "RP" part. Free and browser-based.
- Unholy Heights - Adorable tower defense/management game where you run an apartment building for monsters.
- Fortune Summoners - Side-scrolling action RPG where you play an adventure-loving girl who goes to magic school.
- Cherry Tree High Comedy Club - Visual novel/life sim where the goal is to recruit enough members into a high school club before the deadline. The (current) translation on this one is a little iffy, but it's a fun game nonetheless.

I own Cherry Tree High, It is a fun little game.

Fortune Summoners I have seen and looks pretty good.

I do own Recettear and Chantelise which are from the same company and I love them to death.
