Super Nuclear Riders

-Initially, I thought the control scheme was kind of bizarre.  I like how you have a control page on the menu, but it took me a second to figure out how to actually access it since the confirm key was set to period.  Maybe set enter as an alternative confirm key since that's going to be one of the first keys anyone tries.

-The game looks great and it plays well.  I didn't run into any glitches; a friend of mine had the game freeze at some point--I'm not sure how, exactly.  It ran fine for me, though.

-I think this game doesn't really fit into the short play time.  Strategy RPGs take a lot of time for each battle, so I'm glad that you kept it down to four battles and pared down the story to just bits of dialogue.  At the same time, though, the battle system doesn't provide much intrigue.  There's some potential strategy here with the ranged combat options, ability to reposition enemy mobs, and the back/side attack dynamics, but I found that the game could be easily beaten by just positioning yourself behind mobs and donkey punching them (or giving them the elemental variant of that).  There could have been more depth with positioning myself by walls or obstacles to avoid back attacks, or by grouping my characters in a way that would protect myself while causing high damage, but the balance was such that I didn't have to worry about that.

-That said, I think the framework that you've built here is pretty solid, and you can build onto that by adding more skill variations (AOEs, for example) and more complex level design and enemy types. 

-Right now, your game is just the battles, and the battles just don't offer enough intrigue to stand on that alone.  The small number of enemy types and similar level design meant little variation in combat, which got boring fairly quickly.  If you want to make a game about the battles, then you'll need to sharpen this up so the player's always thinking.  Other strategy games also focus on long-term character progression.

-The game looks great.  The HUD was well-designed and helpful, though I wish some of the skills had more information (such as how many tiles a skill would knock an enemy back or how much life a skill healed).

-I would have liked to see more variance in the attack animations.  While the graphics themselves were good, the lack of much spectacle in the combat made the game slog from a visual perspective along with the slow gameplay.

-I just thought of this, but one way you might make this work more in a short-term way is by streamlining battles--one-punch kills from behind, for example.  This way, you could fit more battles in and the battles themselves would go by quickly.  I think I like the idea of building onto the ideas of this game instead of remaking it, though, so this was just a thought.

Anyway, this was a very impressive game to look at, and the framework you've built is pretty damn cool.  As for a game itself, though, I just found that there wasn't enough there in terms of strategy and the gameplay tended to stagnate fairly quickly despite the short length.
