Hello and welcome to Feedback Quest 6! My name's Hythrain, and I'm one of the hosts and streamers for this event! I'm writing this feedback live after having played your game!
I assume this game is a prototype. It works pretty well for what it is. It could use some tuning in terms of going up and down, where perhaps the longer you hold it the faster you move. What sort of game do you hope to make with this prototype? Knowing that can help me and others give better feedback. :)
