Well that was awesome for the first jam game!
I had fun playing this game. I wish it had upgrade system :)
One small thing I noticed felt a bit off for me - is that the movement of the main character is already relative to the ground, but the obstacles seems to move towards the player as well. Not sure if that is by design but for me personally felt unnecessary.
Maybe also the typing sound could match the typing animation better.
If I would suggest one improvement for this game - you could try to implement the progression mechanics :)
