Hi, first of all thanks for playing! I have few questions for you: did you play it in webgl or downloaded version and did you use controller or keyboard? It feels like the unresponsiveness is due to webgl :/
WeGL version with the keyboard. I tend to not download games as I am trying to play as many as possible. Maybe I can circle back and try it with a controller, I always appreciate controller support as that always seems to be what dooms my games is I test and make with using a controller and everyone plays with kb/m which decreases the playability.. lol
I did go back through and play it with a controller. Def more responsive. Could also be a bit of me as when you release the button the character immediately stop accelerating up and falls. Probably the design choice, but that could have been what was causing my unresponsive feelings. I don't put too much stock into controls for WebGl games during game jams because I know from experience that at least 60-70% of the problem is WebGL and not the game....still a great job!
