Everyone loves RPG Maker games, cuz they're simple, beautiful. GM experiments like Gravity are buggy and weird for me. Terraformer just ugly.
Carius's Space Fish is cool, as always.
Terra Nova is super stylish, but it seems pretty unfinished and dull, you can avoid all enemies on your path. It doesn't have any simple script enemy traps.
Muse the best, I think.
I'm totally up for rough feedback (confusing, too much in the tutorial, "weird", too complex, too easy, too short, sucky graphics, bad premise) and all that, but so far I have had zero bug reports, so if you HAVE found it buggy please let me know what they are so I know how to fix it for future projects.
