First of all, good job for getting something together in the timeframe of the game jam; for a new game dev of 13yo, I definitely count that as a win right off the bat.
I liked the intro, but the game was pretty difficult from the get go - I almost gave up on the second wall because I couldn't erase it (only realized after lots of trial & error that only part of it was erasable). Then, I gave up after 4-5 minutes of trying to jump on that last floating desk to get to the elevated wall, as the tilted desks are slipping when you don't get on the right part of them, making it very hard to stick the landing.
Here are a few comments I thought might be worth pointing out to help you out for your next game jam projet (or any project, really!):
- Try to focus on building the core gameplay before adding intros or cinematics, especially if you have limited time;
- Adding a very basic tutorial or explanation of the controls (even just within the itch.io description) can be very helpful for new players.
- Try to publish a web build early on if you plan on having it playable on the web. This will allow you to discover and debug web build issues early on and to fix them before the deadline.
And a few specific points for this one specifically:
- In your Project Settings, you can allow the window to be resized - you'll almost always want to enable this, as otherwise the game can only be played in a small window.
- When sharing a build, you'll usually want to turn off the "Debug" mode.
- Try to keep your images and/or 3D models (and any other assets, really) light. I have a good computer, yet the game had some trouble loading and starting early on, which I expect is because of this.
In any case, good job on submitting something. I hope to see another submission from you in future jams to see how you progress!
