Nice platformer, especially if it's your first game as the other commentator noted! Good range of mechanics with competent enemies. Didn't like that you couldn't attack whilst jumping. Also, I'm not a fan of having space for jump. The issue is that I always find moving right (W) and jumping (Space) awkward as I use my thumb for both. Not sure there is a fix for it as it is more to do with how I play and possibly not an issue for most players. But good job overall! 

This is really well done for your first game! You had genuinely good level design; notably shortly after acquiring the fireball, the game teaches you the torch mechanic for opening doors. Also there were no noticeable bugs as far as I could tell. I thought the movement was pretty decent, I just didn't like that I couldn't move while attacking, though that is a preference. Other than that, great job!
