A gambling game with your life at stake
I really like your idea and execution. The mini games are fun and not too overwhelming, the Art is well styled and music gives it a good vibe.
Here are a few easy to develop suggestions from a fellow developer:
1. Make it possible to beat the game:
It's nice to have an endless mode with rent price rising, but maybe there can be a mode in which rent price is static and there's a goal to make X amount of cash to buy your own house. Then have a record of how many days it took to reach there as a record.
Winning and making a record always feels better than losing and making a record.
2. Add varied difficulties:
Imagine the current gameplay as normal. In easy mode organs degenerate slower. In hard mode there is a base surgery price each time you buy or sell organs.
To give player a sense of progress you can lock normal and difficult mode until player unlocks them after reaching a certain point in easy mode.
3. UI and UX improvements:
-The chart can be improved to include all body parts in a single chart using different coloring or with icons of each organ.
-Add current price of an organ near its Sell/Buy icon to prevent buying or selling by mistake.
-Make the body health appear yellow then red when in bad condition (You are already doing it with body organs)
-Make your money appear red when you don't have enough for the next rentand make the rent counter do a pop animation when it's getting closer to 0 (regardless of whether you have enough or not)
I know this game means a lot to you and I genuinely hope it becomes a success.
Goodluck you guys
