I really like the simplicity and clean-looking artstyle. I genuinely think that it's just a different style to our submission and aren't comparable in that regard. The way that you used different colour to represent different types of object makes it really clear which ones are dangerous and which are safe. (I'm NOT my team's artist, just to be clear)
Gameplay-wise, the controls feels responsive, double jumps and dashes feels impactful, and the level design made great use of all the available abilities, requiring me to mix and match them in different ways. The difficulty curve is very well done and all of my deaths felt fair. I especially liked the part where the player gets launched into the spikes for not getting off early.
One criticism I can give is that the checkpoints can sometimes be a little far apart. Occasionally, it feels like I'm not able to jump right into action after respawning, due to the wait on the rocket platform, and to be honest, I couldn't think of any way of preventing that. I would personally also prefer the camera to lean more towards the direction of the rocket so that I have more time to prepare. These are just nitpicks though, since I'm able to clear the game without any issues and enjoyed the experience throughout. Great job on the game!
