Clear #123 - Vax
Here's another great homebrew release, with lots of extra value. Besides Vax, you get three other games on the disc and a rerelease of Implode on its own disc.
The Good: the hero cat, NN9, is too cute for anyone to not want to help; rockin' tunes; the action is quick and can get a little frantic; there's only 50 randomly generated and quickly beaten stages, so it's different each play through and doesn't get tedious; and the end cutscene and credit scroll are very nicely done.
The Bad: the 50 stages are enough, but it could use a better ramp in difficulty - some stages are pretty tough and some are rather easy, but it's doesn't seem to matter if you're on level 4 or level 40 for which end of the spectrum you'll get; the end scene is great, but there's no attract intro or anything in game to push the story before then; and there's little variety in enemy types or scenery throughout.
The Ugly: the end is depressing as fuck, even more so with the passing of BT and knowing that a sequel (and NN9 salvation) will never happen now.
Here are my quick thoughts on the other three games:
Zar's - a Yar's Revenge clone that is kinda slow and I suck at something fierce
Wave of Thunder - an addictive score based game where you pilot a boat up stream and try to stay afloat as long as possible, avoiding obstacles by steering and sometimes jumping over them
Slope Dope - a similarly addictive scoring game, but this time you're skiing downhill and avoiding all the trees, bears, etc.
