My best score so far is 41.
There is a lot I like about this game. I really like that you keep the coins after a game over. That’s a really good idea because if you add a shop later like you plan to do it will make the game feel like you are always progressing.
I especially like listening to the sounds, they are all pleasant and I could honestly listen to them all day. I think the way sounds are used is clever too e.g. by making sounds louder in one ear than the other, which is good for direction although I did find this difficult in practice, probably because I am not used to playing audio games yet. The sound when you walk on a car roof is also nice, and I like that you get four steps. I did manage to avoid getting stunned by jumping which made me feel good. I think you could add some music to the main menu screen, which would make it feel more alive. However, I actually think music during gameplay might be too distracting since the audio cues are so important. The sound effects are already very pleasant to listen to.
I also like that there is a “How to Play” button in the game itself. The instructions are clear and explain the mechanics well, especially the part about the four steps on the car roof and the stun if you fall off. It’s also helpful that the controls are simple and systems like coins, score, and leveling are explained.
One small UI suggestion: the “How to Play” button is very close to the “Play the Game!” button. A little bit of space between them would make the menu easier to navigate. It's not a major issue though.
I noticed when you move left or right it makes a sound to confirm the movement, but I’m not sure if I’m moving. It’s a bit hard to imagine exactly where I am on the street. If there are lanes, maybe the game should not play the movement sound if the player is already at the edge.
Overall, I really like the idea and it was nice to play, it’s actually the kind of style of game I think works really well for blind players. Great job, especially for a first game! I hope you continue to polish this.
