I'm glad our opinions are being asked, have some rep, Glitch!
Tweaks you say? Of course MO isn't worth doing anything to it that requires anything major, but here are my suggestions:
- Change the music to be more like Stranger, or even the old games, rather than that crappy techno stuff. It'd do wonders to its atmosphere.
- Increase the view distance (though I think you'll be doing that anyway)
- Am I the only one who got irritated by the whole Spooceshrub thing? However without changing the game entirely and removing/replacing the spooceshrub puzzles with something else (perhaps looking to the first games for inspiration), I'm not sure there's much that can be done about it.
- If geometry can't be changed, maybe you can improve the textures and add a few more props/foliage to make levels less bland
- Agreed with the people who suggested changing the paramites and scrabs back to sounding how they did in the original games
- Overhauling the sounds anyway may be worth it as people already suggested, making them less childish, doing away with the "boings", making footsteps more subtle
- Changing the voices when characters are idle - Even having them actually talk to each other with dialogue instead of having Sims-like nonsensical speech would be a huge improvement. Maybe look at the outlaws in Stranger for inspiration.
- Overhauling animations to be a little more realistic, like the first platformers - Why does Abe roll into a ball while jumping?
- Maybe making fuzzles more feral and less "cute" in gameplay, like their appearance in Stranger
That's about all I can think of for the time being.
