I agree with Lukas and Kenny. Also some jump/eat/hit noises would do you some good, with some music added as well. You can find lots of music on itch, here's a site I use forsound effect generation. Well done on getting something finished and submitted in 3 hours!

Cute start, and decent spritework! I would have enjoyed the game more if it had been a little more fast-paced, or maybe even increased in speed over time. If you wanted the world to feel a little more dynamic, moving the floor alongside the objects would be a nice touch, and if you want to get really fancy add a small running animation for the dragon. Still, you managed to get a fun little game going within the time constraints, well done!

I like endless runner games like this 🙂 Two suggestions:

• I would make the objects come at the player faster. Then, you could make the jump not as high and fall faster, which would feel better to control.
• Since you're using Godot, you could use the ParallaxBackground node to make the background/ground move infinitely to the left, which would give the player a feeling of forward momentum.

Good entry!

Nice lil game, I like the cute dragon :) I wish it started off a bit faster
