Very good for an early attempt at a game! A few things I want to add, though: First, you obviously put in a lot of work, so I'd suggest you just work a little bit harder and use your own game characters and avoid using characters and art you don't have the rights to use. If you're going to put effort into making a good game, why not go all the way and make it your own, instead of making it a "Mario" game? I think you could only improve by creating original characters and art. Second, falling speed is greatly reduced when holding forward into a wall. This is probably easily fixed, but makes it difficult to time jumps in hallways. Also, and this is probably related to the reason why falling speed drops when falling into a wall, if you jump while on a wall, it pushes you away -- this is very inconvenient and frustrating. Good luck on making games!
This game is very fun. I still felt I couldn't give it a 5/5 though. Just picky things, like if I hold jump I keep jumping -- and there's this weird glitch where if you do that on ledges you can jump really high. Wish I could give it a 4.5.
I'm not sure I like how the jumping handles. It should be variable based on how long you hold the jump button, with a maximum limit, because it feels like I have to "wait" to fall when jumping up stair platofrms, which is frustrating. Cute character, though.
Is it just me or do I still run into an enemy even after I kill them? *Hit enemy with sword* "+5" *Keep running and get collision damage anyway* Plus, actually trying to hit enemies isn't very well implemented because it's not entirely obvious where in the "hit" animation I have to land the hit on the enemy to kill them. I can swing my sword right in front of them and it doesn't do anything.
Fun, but the Length[-------]Height bar isn't responsive enough to a click. You click, and then it continues for a moment, which creates inaccuracy in deciding when the user decided to click the bar and where to toss the panda.
