Bugs: In terms of the bugs I could find, the player character turns invisible when he walks far to the left at the beginning of the game. Also, when it comes to a part where there's a platform that's too high to jump onto, the player has to rely on some sort of wall jump in order to get up .
Strengths: I like the art style as it reminds me of one of my favourite games of all time, "Bendy and the Ink Machine". The walking animation of the main character is quite eye catching and the fact that he could wall jump reminds me of "Ratchet and Clank".
Weaknesses: Unfortunately, the black blobs with the sad faces don't seem to do anything and the lack of audio kind of brings this game down. I would expect to at least have some sort of simple jump sound effect.
Also, at the start, when you walk left past the big black rock formation, the player character just disappears until you walk right past the rock formation again.
Furthermore, there are also quite a few leaps of faith where the player has to jump down without having any idea of what is below them.
Changes or Improvements: If I were to suggest some changes to the game, I would add in some platforms that can move in order to spice things up. Maybe also give him the ability to jump higher which would be more helpful than the wall jump ability.
