I thought it was pretty funny overall, but definitely could use polish to really sell the idea.
- The slot machine winnings/losses are hard to tell (the combinations seem somewhat random in terms of what wins?), then another screen pops up telling you if you win or not, which seem preset - either lose, win back what you bet, or double it. I think some variety in gameplay could come from making more combinations possible in the slots and making the winnings generic, like put in $50 and earn 10%, 20%, 150% etc rather than just preset outcomes. Overall think you can show more like your current wallet balance on every screen.
- The tax idea was getting interesting as it went on, reminded me of Papers, Please. I will say the last question I saw was 'what is the number of the form' which I obviously will get wrong, but when I saw my newest stamp it was all letters, so that was confusing.
I could see this being expanded into a short but sweet narrative experience.
