I've loved this mod ever since its very first version in 2.1. It's genuinely a shining beacon of how much one can love a series. All the details, all the references, how you've managed to implement tricks from Super Metroid into a 3D space and make it work in a Sonic game! I've never played a Metroid Prime game, but I have played Metroid, MII:RoS, and beaten SM. This actually encouraged me to play the latter of the three.
Even after making what felt like a perfect mod, you've managed to make it even better! The new maps are a very welcome addition, and the new bosses are exactly what Samus needed to feel like there was a challenge before the endgame and outside of Hyper and Fusion mode.
If I had to give any criticism, it's that a lot of the enemies in Hyper(+) are extremely touchy and sometimes downright obnoxious in the case of Pyre Flies, Egg Guards (I played an outdated version so ignore this one if it doesn't apply anymore), and Gold Buzz's.
-Pyre Flies take up a huge amount of space, sometimes forcing you to fire at them long before trying to platform, and slowing the pace in what is otherwise a fast-paced endgame.
- Egg Guards on the bridge, and pretty much anywhere else, are just... actual pain, and cause the same problem as Pyre Flies, slowing the pace down to a crawl until you demolish each last one of them at points where you just want to speed and not get sniped by a Robo Hood.
- Gold Buzz's are... well, obvious. They'd be fine if there weren't so many of them in THZ1, and if the Emeralds didn't require no-damage runs. Thanks to the combination of circumstances, it makes Gold Buzz's excruciatingly painful unless you have Wave Beam or are really good with your shots.
Even those enemies aren't enough for me to falter on giving this 5 Stars. This is just *the* best character mod SRB2 has ever seen. Worth every minute of wait.
-First, try to start in OpenGL and close any programs, see if it works in a few tries.
-If that doesn't do it, rename sav1.dat to sav2 or sav3. That moves the save slot so nothing will be loaded at first and SRB2 gets more time to initialize. You'll find that file in "Luafiles>Client>MetroidVanguard"
I'll probably try to make another patch in the future to try mitigate SRB2's I/O limitations. Sorry for the trouble!
