Hahaha it's fun. Although I couldn't complete it because it asked me for a skill I don't have, it's a shame.
What? Is it a sequel to a game you made in the previous jam? Man, that's cool xD
The game is difficult. I managed to get through the first part without much trouble (Because I found out that if you hold down the jump key, jumping on the yellow buttons becomes easier) but when it came to the wall jump part I couldn't anymore.
The sound is somewhat annoying and the graphics lack cohesion (the knight is adorable though)
In general, it's a good game. Although I highly recommend you learn about "game design" or tips to make platforming feel good.
