Really cute game with great art! I played it for just under 2 hours to see all the dialogue possibilities at the end. It took me a long time because I suck at the game lol (I liked the challenge though!) I think the game would be fun even without knowledge of the source material, so I'm going to recommend this game to people who I think would be interested. It helps that it's also short and can be played on the browser (I didn't need to download any files or play though the app)!!
I agree with David's comment, particularly the suggestion to press spacebar to restart (using a mouse for this one action is mildly annoying).
I think the game's ending dialogue is a really strong aspect and could be utilized for any future games should you decide to make more. I thought your writing kept the Magz in character, and I wanted to see his reaction to things and the cool art poses he does! I'm not sure how difficult it would be to code, but an unlock gallery would be neat that allows you to view the art and/or ending scenes once you complete that route! The game is short enough that this isn't really needed though!
I didn't realise the catfood and L-car killed me at first, and while it makes sense lore wise (cool references btw!), maybe you could have it so you can pick up these items as well (but you can only carry one item to the end per run)? I want to see the maglord mald at my shitty gift choice! This is a personal suggestion that I think could increase the game's replayability and make it so you don't accidently die the first time thinking you can hit it, but honestly I'm just nitpicking at this point. I do really like the game as is! It's amazing that you made this for free as a fan and in such a short time frame!!
This is unrelated, but I really love the art you post on Twitter as well! That's how I found this game, actually!!
