nice lil game you have there , its really some great effort even tho its your first game , some suggestions tho , even if this was a web game I suggest you add some textures and make some tweaking with graphics , I also suggest you add score system (if you know how to do it) to know how many obstacles the player dodged
We only had 2 days to make this game and honestly I was a bit strapped for time due to the game jam. I would've loved to add textures and made it more difficult as time progressed but the major set back was the newbie mistake of thinking I could make a 3rd person game where you collect your robo parts scattered across the land. So basically I found out how ambitious it was to try and make a 3rd person game for like the first 14 hours of the game jam. TBH I am surprised I got it to the point I did in the final 8 hours. I learned a lot though and it was so much fun to mess up and get a creative process worked on.
