Cute and short game.
I liked the pixel art you used as well as the UI and music selection. The game is quite easy to beat and there's not much challenge after you recruit a second member, but it's still enjoyable to play.
Some improvement suggestions:
- The status screen is missing a close button. The game somehow stays there for a while and then sends me back to the title.
- Avoid having the default volume at 100%. It's loud. I suggest having it at 50% and then the player can adjust it to their liking.
- It would be nice if the BGM didn't change every time you change screen. The main gameplay loop requires clicking between screens quite frequently and it's not very enjoyable to have the BGM cut every 5 seconds. I'd suggest adding a playlist with two or three songs that loops in the back while the player is in the "main" gameplay screen.
- There's not much to do after you get all talents and shop items. Maybe consider adding more upgrades in the shop (relatively expensive ones) to speed up the construction speed.
- Tax is only a threat at the start of the game. Once you have a second talent in the team, you make so much money that tax becomes irrelevant. I would probably make the tax increase a bit faster to make the player think a bit more carefully where to spend the money.
For a first game, you did a very good job! I'm sure you'll keep improving and surprise the community with new amazing games! :D
