This is perfection on a platinum plater, I've loved this ever since I first saw in 2.1 on youtube all those years ago- since i like giving reviews with substance lets actually talk about it
[Sprites]: Do I need to say anything? Junio is already one of my Fav' designs so I mean he's got that to begin with, the sprites- despite not being withing the "2.2/SRB2 style" I honest to God think he benefits from such, allowing him to stand out and truly expressive what it means to be "Junio", the sprites themselves were expertly crafted, each frame doing a good job on representing on what it needs to do and I think they all do a fantastic job! my only and i mean ONLY complaint (which can be seen as a nit-pick) is that i feel like just a bit more energy could be poured into some of the sprites, just that extra kick to fully capture the essence that junio brings to the table.
[Playstyle]: I LOVE how he plays its like it was made for me, and a lot of other people- the peel-out is a great way to get speed instantly and helps a decent bit by the "momentum cut problem"..... spindash kinda sucks though, ngl i would be fine if it was cut in favor of the bullet dash being able to break breakable walls and the peelout being able to activate the spindash powered.. thing? in DSZ2- i wouldn't mind it being removed. As for the Bullet dash, well I love it i think it grants a lot of freedom, I know it kinda kills the mod a bit for some since it really does kill your speed a bit but at this point it barely affects me, 2 things though- 1. I feel like the power of which you hold the Bullet Dash could be increased, the lower levels are sorely weak at times, 2. I feel like the moveset could do with one more move to round this this off and maybe address the stop-and go issue.. maybe from sonic freedom? the guy who did the sprites and made the bullet dash's concept already worked on this so why not? (this feels more like a suggestion then a complaint tbh)
Overall this is my #1 mod and thats never changing, despite its status of a earlier 2.2 mod in my opinion it aged the best it could have and its PERFECT for me and a lot of others, honestly a shame this hasn't gotten a "major" update yet- i really wish that this could be expanded despite how much i love it... (maybe 2.3?) other than that nothing else to say- thank you for reading!
(TL:DR for those who don't wanna read all that, Junio Sonic is Peak and forever be so.)
