Thanks so much for playing and the detailed feedback!
You are very right, sound and music would be a welcome addition which we had to cut to finish the game in time for the jam, but which we have on our list. Also rewards and an improved gameloop with probably a hybrid-procedural level-generation is something we are thinking about at the moment.
We are glad you liked and enjoyed it so far and would be interested in more feedback down the line.
Best from Zwi/Team Oddytree
