Do you plan adding Trading Cards? Thank you

I feel awkward jumping with 1 hand and moving/toggling with the other. Not to mention why not let the "toggle" actually toggle rather than made to be pressed down.

How many levels? It looks like something I would like to speedrun but there's very little info on the store page.

I'm going through all the games I had negative experiences with and checking whether or not they've seen any form of love since they soured my impression. I saw that Eron had an announcement regarding this game here... I was actually hyped for Eron and bought it as soon as I was able to, but the game was so broken and basically dead on arrival, can anyone let me know if there have been any updates to fix it in the last year or so?...
