Wow this is an amazing comment! Thank you so much! I really do like all your feedback and I feel I must give answers to all of your points.
It's great that you beat the game! 4 hours?! Nice! I've still not been able to do a no death run yet :D. You make a good point about the message disappearing and I'll be sure to make it so the player has to press a key to go back to the main menu!
I've seen the other messages regarding making the d-pad move the player and I'll be implementing that next update (whenever that is).
A speedrunner timer is good but it would be persistent. What I mean by this is when you close the game, your time will be lost. The reason it will be this way is because I have no idea how to save things when the game closes :D. So you might have to make your own .txt and write down your times. I'll also be adding a death counter!
I will 100% be adding new levels to the game! I've already got 2 in the making and I might add a third. So I hope you enjoy them when they come out! (You will have to re-download the game from the same link when the updated version is out)
I'm really glad you had so much fun playing the game! That's really awesome!
