I already gave you my feedback in the discord, however Ill put it here as well that way you can reference it again (and I added some parts)
This game is great! I especially love how you can play it on phone even while it is a webGl game! Great job and good luck in the jam!!!
Some feedback:
I think that this game could have a little more ooomph to the game with some music. Some cool skater music would do the trick. Maybe you could use soundtrap to make the music since this is a only-our-assets game jam.
Going along with that, to add some personality and feel to the game, I think that you should also add a main menu as well as a cut-seen explaining the role of the skateboarder. I would love to see a scene before the game where it shows like cops following you or something and the character says "I need to go NOW" then the skateboarding game scene starts. Another thing you could do to add some feel to the game is to customize this game page. You can do this by going to edit theme (top middle) and changing colors, banners and adding screenshots. This makes each game feel unique.
I know I gave almost identical feedback to someone else too, however I think you should add a public leader-board as well as a personal leader-board so that people can see their high scores. This would add a little competitiveness to the game.
Once again, this feedback is supposed to be constructive! This game is great and I would love to see the changes it undergoes in the development process. Overall, great game and especially impressive to be done in a jam!
