I completed the game, Overall nice concept. I understand this is your first jam and you still managed to complete it. Keep on doing it :D

The core idea of your game is cool, and I like what you did with the tile-set, especially the background sky where it transitions from dark blue to white. Theme-wise, it fits pretty well too.

But I think a better interpretation of the word 'charge' for you would be to start the character slowly (I mean, it's a heavy armor knight at the end of the day) and collect boosts to charge faster.
The game/level starts off waaaay too fast. :D

I also wouldn't use the walls as an instant game over, maybe as a collision with knockback? So in the end, the main objective would be to finish the level as fast as possible by collecting your boosts, evading hazards, and getting faster and faster, kinda like Sonic, but with a knight?

Still, good job on finishing your jam, congrats! :D

Have you playtested the game? Some boxes and collectibles are unobtainable because you will just get into obstacles. And the default scrolling speed is too fast to be comfortable.
