Played it and found it REALLY hard. Of course, that's because I made a similar game and the the physics are similar but JUST different enough to throw me off.

One bit of advice I have is to only jump when the player first presses the jump key. I died a few times because I suddenly jumped when landing because I didn't let go of the jump button immediately.

This is a nice little challenging platformer, the platforming here actually feels really solid!

a true classic platformer. I tried to finish the game but I cant seem to get past the spiders. Controls and physics are solid. Keep it up!
