This is my go-to character mod to play, for a number of reasons.
Sprites - They are BEAUTIFUL. I adore the choices made on the default color and general look, it is very faithful to Espio as a character and SRB2 as a game. The top spin smears are awesome, and I love the attention to detail on how when he has to roll he doesn't do it in a complete ball similar to Amy and Fang. The hang sprite is really cool since he uses one hand, and the edge sprite is very cool too.
Gameplay - Espio feels right at home in this game. His abilities allow for creative movement options for any map, allowing the player to really experiment with his capabilities. Forcing him to go to Amy & Fang routes when they're split with a roll gap is an excellent choice, makes sense for the character and gives more appreciation to these routes. I was iffy about him not having full control on walls at first; but not only does that sound like heck to program, he really doesn't need it. He can quickly scale walls, and run onto a ceiling from there. This in particular opens a HUGE amount of possibilities for movement in Battlemod. I sort of wish he could spindash on walls, but only downwards; providing an way to charge speed in a cramped space along with a offense/defense for wall climbing it battle. However, what he has already works fluidly.
This part in particular deserves its own paragraph; his main charge jump ability is very well made and fits him perfectly. It's a double jump that provides the same amount of polish and flair that the vanilla cast hs naturally. It's satisfying, suits the spinning top shape, fun to use, and is just great.
This mods does a marvelous job reflecting the coolness of classic era Espio, one that isn't seen often due to his underutilization. He's a member of the classic-era sonic cast, and this mod treats him as such. 10/10 Will stick with me to the end.
