I liked it! It was pretty easy to understand, and it wasn't too hard. I like that it saves your progress too so that you don't have to beat the whole game in one sitting. The controls felt alright for the most part. The spike's hitboxes felt a little weird sometimes, and it would be nice if the player automatically respawned after half a second or so when they die instead of having to hit continue. Also I feel like in this game it'd make sense if you have to press the space key each time to jump instead of being able to hold it to jump continually because that's killed me a couple of times. Also music and sound effects would have been nice.
