Are you not supposed to be able to hold left/right? When I hold it takes about a second before the player begins moving
Yeah I originally did that so players wouldn't accidentally move somewhere they didn't want and have to restart the level, but I think that you're right. The controls are a bit clunky, so I just fixed it and re-uploaded a new version.
Would you give it a try and let me know if that feels better? I definitely prefer it.
