It was alright. The only thing I would improve on is the platforming and the collisions. I feel like like the jumping wasn't high enough to reach higher platforms and I sometimes had to cheat it by jumping onto a wall and keep spamming the jump button hoping to be lucky to make a jump from that. Also, I can tell you didn't use the Platform Movement Object, and I'd highly recommend giving it a try for your next game, it will make collision detection a whole lot better, since I kept getting stuck when touching the bottom of the platforms and couldn't move anymore until I landed on the ground. Despite that, I was able to beat the whole game, and overall, if this is your first game, not a bad start.
