Fun fact, english isn't my main language either man X)! I actually learned a lot from YouTube. As a programmer or even a computer scientist in general, you have to be able to express yourself in english to be able to learn a lot and share your work with as many people as people. That's why we keep learning man! :)
As for your game, naahhhhh it's not too hard. It's exactly where it's supposed to be! X)
In some levels I was really impressed because you made just the right level layout to make it impossible to complete with an unintended way at the perfect distance! Not too close but not too far either. That was great!
And as for me, yeah X). I also really enjoyed this Jam! That's my first one but I'm glad I was able to make a game and submit it in time! And ratting games is actually way more fun than I tough it would be! I've been doing this since Tuesday X).
I wish you luck going forward dude! :D
