Rebel Assault 1 and 2 (Steam) <2.51>
I think I'm having some kind of nostalgic mid-life crisis. Possibly brought about by that Duncan MacDonald book I just read (I'm currently reading through scans of all the issues of PC Zone - I think Quake's just about to come out). Anyway, I was a bit dubious about how well this might work on the Steam Deck, so I thought I'd better test them.
Rebel Assault is a bit of a mess at first, as you need to use the keyboard to navigate the launcher (or I guess I could have set a different layout), but once you're in, it seems to work ok (I managed to get through the training missions anyway). There was a community mouse/gyro layout, but I was terrible with that, so went back to the default (with added escape button to skip the cut scenes).
Two seemed to work ok out of the box with the left joystick allowing you to control the cursor in the launcher.
My testing stretched to 82 minutes, so I guess they weren't't too bad.
Strikey Sisters (Steam) <1.99>
I keep reading about various games, then adding them to my wishlist, then when they go on sale (like this is), I don't recognise the name (like this one) and have to see if I can remember why it made it onto the list in the first place.
Turns out this is the "breakout one", I didn't play it much as I ate up my downtime with the Rebel Assaults, but yeah, it's kind of like breakout (or Arkanoid, if you prefer that reference), but you're the bat. Sorry, that's all I've got, I only had a quick go.
