Thanks a lot for the feedback! Regarding controls - you're totally right, possibility to spread out input is a must and I don't know why I haven't though about it during the jam.
I've planned to upload a WebGL build, but there were some issues with loading the game in browser. As it was really close to deadline I gave up on trying to fix this. If it's still allowed to upload a WebGL build, then I'll give it a shot once more, though I'm afraid that it could be a problem with custom shaders or sth like this and there's nothing I can do about it :/
Thanks once more for the comment, I'm really glad that you liked my game! :)
