EDIT: the author has updated the level to take the feedback into account!
This is a nice simple beginner level. I like the escalating difficulty and the challenging but manageable jumps involved. I think a few small changes could really make this level stand out.
First, I would move the checkpoint to somewhere earlier in the level and maybe add a second one if this level is for beginners. Right now the current placement is after all of the difficult parts, and it would be much more useful after the first challenge.
Second, I really like that there is a direct route that speed runners can take. I might make this a little bit more difficult. I would also add tons of gems for players who go the long route. In an ideal world, a player who rapidly takes the long route should get a better score than the player who beats this level in 2 seconds using the short route. This adds replay value to the level.
Finally, I would consider having an extra challenge bonus with the pinball bumper and the moving fire. You could have a platform just barely visible to the right, that you can only get to by jumping on the bumper. This would require some testing to make sure you can do it, because it’s very hard to land on the bumper right now. Some big jems and maybe the ripcord powerup could make this feel very satisfying for the players who like to explore.
Overall a great beginner level, I enjoyed it.
