Quite a fun-to-play game. The minimal graphics and the overall concept of a simple platformer are quite good. However, you need to polish on certain points to make this game super interesting to play, currently, it feels a bit boring. A few things you should check and rectify-
- If the player stands near the crate, the player can't jump.
- Implement the sound only when the player jumps, not when the user hits the jump button.
- Player Controls could be better.
- How about adding Enemy follow mechanics depending upon proximity.
- Adding some visual effects like particle effects and other things.
- The colliders of crates and platforms are quite odd as if the player stands at the edges of anything, it starts to slide over.
