Thanks a lot! Yeah if I ever make a bigger version of the game for Steam it'd definitely have controller support and more music - no plans for that right now, but maybe one day!
Apparently I'm bad at judging the speed because I've increased it a few times now, but this time I've sped up almost everything (player walk + sprint, balls, cones, kick animations). So hopefully that feels better now!
There is also now a level select which you can get to by pressing escape in a level (or on start-up if you've beaten level 1 previously).
An undo would definitely be great to have, just not the easiest thing to implement with how (badly) my old code is written. So it's not been added yet but I'll see if it's possible to get working in another update.
Thanks for the feedback! I slowed down the animation of the corner icons to try to reduce distraction, and added a new hotkey (H) to show/hide them. Also increased the movement speed of the player and ball which hopefully makes it feel less slow :)
