Thank you for the feedback! I'm really glad you enjoyed it :)
I actually found your channel yesterday and watched the VOD of your stream, thanks for playing my game there! It was very fun to watch and naturally gave me A LOT of feedback too. I see the wall jump could definitely use some tweaks, I agree the checkpoint's safe area is not quite the easiest to get out, and you also managed to skip a little part around the second key that wasn't supposed to be skippable (but fortunately wasn't crucial either). Also, you made me realize that I did actually add controller support but forgot to put it on the page's description, brilliant.
Thanks for all that!
