The main character could be larger so you can see all the details. Average platformer gameplay style. If you added lots of collectables that might increase the need to explore every corner.

Good Game but the physics is a tiny bit wonky also no arrow keys support. also why am I playing as a wolf I thought this was called Stickman

Interesting game. It gives me vibes about ''Give Up''. In my opinion, the game in general is quite simple, but decent. However, I think that it needs something more, like more obstacles and levels variety. And also, I think that you should add that the character can run, and perhaps, make double jumps as well for improving the movility. But asides from that, I think that the rest is decently solid. Keep improving your game-making skills, lad. I believe in you! Much encouragment! (And also, welcome to Newgrounds and to the Portal as well! I hope that you have a good time around here).
