I really like the game concept it is straightforward and easy to understand.
Notes:
- Occasionally I pressed space instead of "W" to jump as it seemed more intuitive, but the "A" and "D" I had no issues with
- I did not read the full text for the power ups as it was too long
- Some visual feedback when collecting a power up might be nice to have
Looking forward for the final version of the game with some nice visuals and sound!
