This one is another of the few "classic SRPG" entries, while the core gameplay is what one could expect, it has some nice little twists and a lot of polish.
The use of the theme for the plot has to be the most expanded of all the entries, yes there is a tournament... but there is also different relations, a bit of lore and world building and a lot of dialogue for a 6 chapters of the game, if this was meant to get me invested to check out the main version of R0 then I have said it succeds at that.
I really liked all the polish that went into the art and UI, the effects at the start of a battle and the "Chapter Complete" were something really nice that I would love to see more in Srpg Studio games.
The use of the music to setup the mood of the different scenes was done to great effect.
And the gimmick of choosing what teams to play in the different encounters, all the way up to the finals was really interesting and allows for some good replay value and personal playthroughs.
On the other hand, the map desing is certainly the weak point of the game, I guess they fit into the whole "Arena" concept, but up to the final chapter all were pretty big and empty with both teams in oppossite sides... at least the first turns of only moving towards the middle were made faster by the use of the Auto mode.
Overall, I really enjoyed this one, the story got me hooked, and the battles were engaging (once people get in range), and the final chapter was an interesting challenge. There is a lot of polish and details to love.
