Quite good! I like the music and the game has an appropriate difficulty - neither too easy nor too hard. However, there are two problems. Problem 1: the tutorial isn't well done, it took me a long time to understand how to play. For this reason, I died yet during the tutorial in the first run. Problem 2: when you die, the screen freezes and you have to reload the site to play again. That doesn't make a good impression. Next time, don't let the screen freeze when the player dies. Instead, add a "You are dead!" mini-cut-scene and let the player restart it directly from the game. By the way, on the second run, my score was about 1700 (I don't remember it exactly). Except for these two issues, Space Candoot is well done!
