One Card income is a jam game for the GMTK 2019 Jam, under the theme 'Only One' honestly couldn't work on it as long as I wish I could have but that is how things just tend to go. This is only my second jam and I had a great time.

The game is a Card game where you only have one card in your hand. You have to move your units around carefully while managing your gold.

I may update this game after the jam, I do like where this game can go and I have ideas for it. Many of the assets I have are placeholder cause of time issues. Tips for anyone doing jams, DONT move into a new play a day before it causes problems.

the 'Esc' key can be used to return to the main menu if you need it.

Really love the mechanic although I'm still stuck at wave 2 xD. With a little more balancing and music I think this would be a very great card game

Thanks! I see potential in this project as well :D


Is the whole gameplay idea based on the economy yours? Because it's fucking fantastic. This is very damn promising, i highly incourage you to actually turn it into a full-blown game with more features/levels and possibly PvP and deckbuilding, it's up to you.

It does have one fatal flaw tho: the randomness. Haveing compleatly randomized cards without any idea on what you're gonna draw it's problematic and makes planning very weird sometimes.

If i had to suggest a solution i would tell you to either just make the hand size bigger (i know that it's just 1 for the jam but outside of the jam it doesn't have to be) or alternatively to have the ability to know what cards are left in your deck

I hope to be able to play a full version of this game in the future :D


Thanks alot! The original idea was for it to be a deck building game actually. I do want to work on it more over time, and it has some problems to fix (the Randomness being a big one) another solution that comes to mind it having the next enemy be told to the player. While I probably won't do PvP I do have some plans to work on the game more. Thanks again for playing

Damn this game is really good! Color me very impressed!

This is a really simple, elegant, intuitive set of mechanics, and it just works great! Obviously the program itself is rough and unpolished (like all of ours for a game jam), but this is just excellent, really! This is by far my favorite game jam game I've played thus far. Really well done, I mean it.


thank you alot, and yeah unpolished as all heck. Thanks for playing and it means alot that this has been your favorite!


I liked the game only felt like it was alot off luck off the draw depending on wether you win or not.


Yeah, given more time I would like to balance things better and maybe give the player more control. Thanks for playing though?

no problem I really liked the idea as well I hope you had fun making it :D.
