@liviud's comment; perhaps if you want money, you could add in-game bonuses, like minigames that cost kreds to unlock, or multiplayer with features that cost kreds to unlock; as in "50 tokens to start a guild" or something like that.
I think with a few improvements, like an inventory, more dungeons, and maybe a crafting system, this game could get quite the following. 2 things though. 1, fix the walking through walls glitch. It's really annoying. 2; if this gamedoes get a huge following, do not, I repeat, DO NOT make it a pay to win. if you do, I will never play the game, and really, not many people will.
I have a few ideas for the game. Add a bigger arsenal, and more craftable stuff, like more pistols, motorcycles, and maybe something between the starter pistol, and the sniper. I found that one was to weak and the other was too strong. That is all.
@ alyssaeve Derpy isn't going anywhere. She just likely won't have any major speaking roles. Save derpy is a ridiculous cause. It's like saying "OH NO NASA'S SPACE PROGRAM SHUT DOWN WE'RE NEVER GOING BACK INTO SPACE EVER EVER EVER EVER EVER OMGZ!!!!!11!!!!!!!1!!!!one!!!!!11!!!!!!uno!!1"
