Taking a third shield will add a ring magnet and 8-directional dash similar to a hyper sonic!!
Thou hit once looses it all to leave a distinct gameplay.
I think about bunch of minor features that I consider yaw too much on a requirements, I just don't have that points to pay... Thou I'm a perfectionist sorry:
That will give you the full look on my vision of a mod. Nothing below is necessary to fulfill the request, thou I kindly ask to stick to my vision of a modification, because it's a real gamechanger:
1) Last took shield leaves it's protection type - breath underwater\ immune to fire\ immune to electricity
1.1) Every special immunity stay, in a sake of player (for example taking water and electricity will not ruin it underwater, where you can breathe and continue to magnet rings!)
1.2) Rare flash of a last shield — to remember and for a cool look!
3) Fast "super" animation as on thumbnail of a request
4!) Tails and Knuckles should not be left behind. Let 'em longer flying to Tails and faster climbing to Knux
5!) New special abilities better be on another button, to leave the drop dash, that we all love now!
6) Doubled shield should be classic blue, while tripled should be red\yellow
7) Fourth shield will add a prolonged timed invincibility
8) I will be helping with that — we should draw new, combined shields. Having 3 initial shields and 2 to combine we just need 3 different shields as a combined (water+fire, water+electricity, fire+electricity)
X) Hope some day we can have more enemies on acts to deal with such a great powers :)
XXX) that' for a very different kind of mod, maybe there is some — hurt removes 50 rings, so if you have less then 50 — you're dead!
