1. Run at a slowed pace 2. Combo of Mario and Ghost'n'goblins (A Little XD) with some acrobatics/aerobatics. 3. Preferably not across flatground but down stairs, depending on how fast they entities are traveling they might hit stairs on the way down (a bump, I guess)
This is what the third sample looks like so far, not all textures are made yet - while a few are place holders.
So i'm technicly following the third alternative at the moment.
The left one would most likely result in a very mario like game. You know run from left to right collecting points, dodging/killing enemys before the timer is up and a few puzzles.
While the right one would most likely result in a game that's more like metroid but has alot more puzzles to solve. It'd probbly involve more fluid movements (Wall runs and alike)
Edit: So no it's not only cosmetic it's also helps link gameplay mechanics in.
Edit3: Now that I think of it a little like colbolt, with the one on the right.
and another Edit:
On the cosmetic side the one on the left requires many "transition" textures and uses alot of colours while the one on the right won't require as many transisions and so far each texture only uses 5-6 colours in it.
