The Real Texas is part of Indie Royale's Spring Sun Bundle. It's (more or less) a PWYW bundle, so get in there and PWYW!
(PWYW == pay what you want; Indie Royale has about a $5 minimum though.)
Other games included are explorathon Knytt Underground, multiplayer tower defence arena (I think) Monday Night Combat (NOT the super variety; allegedly this one is different enough from SMNC that you might just want both), excellent Japanese indie R-type-alike SATAZIUS (this is a true gem!), and an experimental 100% auto-generated metroid-prime-inspired game called Gentrieve 2.
I'm streaming them this week on my Twitch.tv channel. (along with some other games.)
Please check it out, it's a great little bundle and well worth the suggested $15 (but please DO feel free to grab it for $5-ish which is the usual minimum)
