mothwentbad: After a quick Google, I couldn't find an official forum for this game. It's possible that the developer doesn't want to deal with drama or grief, but hopefully some well thought-out feedback could be of use, and I'd like to see what else I haven't thought of. I hope updates are being planned.

* Only one save slot? Of course crude workarounds are doable, but meh. It's often nice to go back and see how far you've come in games like this.
* Exit to main menu --> resume game is essentially a free trip to the entrance, and therefore a free trip to any found teleporter. This isn't exactly OP as far as exploits go, but you might as well include a no-nonsense version as a feature up-front. Optionally, they could maybe even make exiting the game require a five-second uninterrupted channel if they really want to curb exploits and polish things up a bit.
* It's a bit early for me to know, but I'm really curious whether it's possible to genetically manipulate offspring later on. It's a real hassle to deal with classes you suck with sometimes.
* As far as I can tell, there's no consequence for failing over and over in between good runs. A challenge mode where certain benchmarks must be met by certain years would make this Roguelike even more Roguelike. I'm pretty sure that I just plain suck, but beating the first boss in the year 2100 doesn't sound all that legit to me! X-D A game mode like this would prevent the player from feeding a character to the wolves every time a bad roll came up. Forcing the player to optimize each and every run would really tighten the gameplay experience.

Some or all of these features may already be present, but require unlocking. That would be sneaky. But off the top of my head, these are the features that would add a lot to the game IMO.
