I'd totally be down with a much longer and better created Bound by Flame. They made a rather great back story for a very small game (took me 13 hours), if we could've just expanded on that (and fixed game mechanics) then I'd be happy.
Instead of fighting just the one Ice Lord they could've gone and made it much more satisfying with a bunch of trips to defeat all of them, heck they could've even taken out the linear part of the story at this juncture and made a town in the midst of everything act as a hub. Not even a town, just a small camp or something. Instead they basically cut the game down to about a sixth or a seventh of what it could've been. Characters in general could've been more fleshed out and more well written.
The demonic transformation you go through could've been done better as well. Instead of it being story elements that make you change they could've made it where optional quests or challenges would've made the power surge up more to the point of completely becoming a demon (instead of being a human demonified). I understand why they didn't, it was a driving element, but it seemed rather forced as it was.
A main gripe was the combat. You didn't really do a lot of damage with the two handed sword, the daggers, or any other weapon for that matter. The enemies had some ridiculous amount of health while you were off smacking them with a stick no matter how far you were into the game, or so it felt. It was more or less an illusion of difficulty, simply because of the fact that most of the enemies had way too much health and you did little to no damage. Fights dragged on and you could die in a two or three move combo if the enemies set it up right. Get rid of the illusory difficulty, make enemies easier to kill, and add more difficult situations (as in being swarmed, or an actually decent boss fight).
Armor and weapons could've been expanded upon. Being able to forge your own weapons would've been nice. If they had made an anvil crafting area to make weapons, where you just funneled all of the loose materials you'd been hording for the past levels could've been spent, it would've been a nice addition. Instead there were a couple of static drops around that you ended up getting via kicking a random corpse in an icicle or finishing a quest. Those weapons, or pieces of armor, were then able to be upgraded by adding pauldrons, tassets, and a hip pouch. That added some variability, but not what I'm looking for. They could have also made an endgame suit of armor, or a sword, that you had to go through a quest to get, that would be undeniably better than every other armor or weapon. Instead I ended up entering a new chapter and somehow grabbed the best sword from it instantly and upgraded it within 10 minutes. Everything found after that was recycled.
I think the thing that I liked most from this game was enemy design. Get rid of the shambling corpses found in 9/10 RPGs nowadays, and you had some really interesting enemies to fight. The one Ice Lord you fight was a rather boring and unimaginative fight, but otherwise I had fun with most of the bosses.
So yeah, if they had made it into a full-length 60 hour game, with more customization and exploration without any illusory difficulty, would've been a game that I would have dearly enjoyed. Oh, they could've fixed the whole talking without moving the teeth thing, too.
