The simplicity and the artstyle makes it pretty nice, also the gameplay somewhat reminds me of Spelunky Classic.

it's so hard that it made me suffer The Good Parts:
Especially for a first game, it's really fun
The particles look good.
The sprites don't look too bad for a test game.
The Bad Parts:
You could try a better font and color for text.
The hitboxes feel kinda off.
I think the score text should always be on screen.
Remember that I'm not an experienced game developer at all, I can even say that your game is better than my project's current state.
