Godot

Character2D must enter an Area2D to win.
Create a 2D scene with platforms to be able to jump on to get into Area2D.

The default script of Character2D should be enough, so should not take too much to make.

When you have any kind of game where you can make progress by unlocking things, make it so you can save it and load. Make it so you can save at least in two slots (or infinity by letting the user chose a file).

This will teach you how to store wins&unlocks, and that you must clean out any wins/unlocks from your character sheet.

Test case: unlock a fearure with save A

Load save B, check if it's unlocked (it shouldn't be).

Make a game where there is a countdown and you have to stop it as close to 0 as possible. Something like this Mario Party minigame: https://www.youtube.com/watch?v=hoNduqVEdTU

For extra fun, make it so the display says ???? and the player has to count the remaining time himself. The duration can also be randomized, sometimes 5 seconds, sometimes 3, sometimes 12. Good luck.

Make a dice roller game/app.

Have you made an idle/clicker game?

It will teach you timing and menus.

Do GTA 7

I’d try going to itch.io and joining a game jam. They will usually give you a theme to work around and it’s a great way to learn stuff. Every time I try to do one I try something new.

If you want something in 3D space:

1. Make a character in an open area, you can walk and jump

2. Create platforms you can jump on

3. Make a coin/sphere/mass on top of one of the platforms

4. Make it so if you touch the coin, you see a "you win!" Message or similar

5. Put multiple coins and have a counter for each collected

I did something like this in UE4 as a beginner, hoping it's not too different in godot. Put a 60 second timer on this and you have yourself a mini game!

I'm late to this thread, but, if you want a challenge, here's an idea...

Make two simple games... like, maybe Pong and Asteroids, but, set it up so that the player can swap between the two games at will (maybe by pressing the TAB key, for example). However, both games should still be actively running even when not actively being played. Maybe, for fairness and an additional challenge, if one of the games isn't actively being played, it still updates, but the updates are at half speed.

Is this a solid game idea? Probably not... but it would be a fun challenge to see if it can be pulled off smoothly.

Make a physics based dice rolling app for a role playing game that rolls any number of polyhedral dice in a virtual dice tray, and provides the sum total of the roll at the bottom.

Make it so it runs on a phone, and you can roll the dice by shaking the device.

Make Minesweeper.

• Board size should be configurable on both axes
• Number of bombs should be configurable
• First click should always be 'safe'
• User should be able to mark unsafe tiles as bombs
• Game should detect a win and a loss

It's a surprisingly simple game to make, but it's great for learning arrays and user input and Godot's GUI system (the board can be a grid container.)

Idle/clicker sounds like a good idea.

On a tiny bit more advanced one, i would recommend something with a little bit of world persistency, like an exploration game with multiple rooms were the player has to place/retrieve objects. I found myself struggling with learning the benefits and limitations of the scene system and i think this could help.

More generally, I think a 2D platformer game is a good one to try : not too complicated, especially if there are no fights, but still requires to get used to most basic elements.
