Nice game! Here are my notes from playing:
- I appreciate the how to play screen - I don't think you need to be so hard on it! Making fun of yourself is all well and good, but do it too much and you'll only convince people to dislike what you've made.
-Allowing the player to use WASD or the arrow keys is a nice touch!
- The colors could be a bit less saturated, and the art isn't anything too great, but the fact that you did it all yourself is really impressive.
- The scrolling tutorial is a really clever way to handle it, but the scrolling speed could be a bit faster.
- There were a few typos, I'd recommend using a spell checker.
- The idea of needing to move quickly so your biscuits don't get stale is really clever!
-The game starting immediately after loading is finished can catch you off guard and cost precious milliseconds - perhaps a countdown before the level starts would help? That way the player can get ready and is prepared to start running the second the timer starts.
- It would be nice to see a timer on screen while you play!
- I don't know if it really makes sense to have the goal time be a secret - it doesn't really add much to the challenge, I don't think.
- I like the music, but I wish there were more songs and more sound effects! What's here is good, I just wish the levels themselves had music. A jump sound, a walking sound, and a sound for grabbing the biscuit would be nice.
- Including coyote time was an excellent choice! If you want to make the movement feel even better, I'd recommend looking into jump buffering (allowing the game to register a jump input even if they haven't QUITE touched the ground yet, if they're only a couple frames away from landing, so they'll automatically jump as soon as they do touch the ground).
- The ability to restart the level if you mess up a jump would be nice, rather than having to finish a run that you know isn't going to beat the goal time.
- Missing a jump was a bit annoying at times since I couldn't just restart a bad run, but since each level is only a few seconds long, it wasn't a huge issue.
- I like the blocks that you can secretly pass through! Great simple way to hide secret shortcuts in the game and get players to search each level.
- I like how the win and lose screen both have the same opening animation (which is really neat, by the way), so it leaves you in suspense about whether or not you met the goal time. That's one advantage of the secret goal time, I suppose!
Overall, while the game is lacking a bit of polish (especially with the art - but that's okay, the fact that you made it yourself is worth a whole lot) and could use more sound and more levels, I think you've made something really fun! I had a lot of fun playing it and trying to beat my fastest times. I think that, if you keep polishing this up, it could become something really good! I think you could easily make more levels, and I think the art could end up really good if you just put a bit more time into it, because you have a knack for visual effects and you're clearly having fun with it. Also, more music! What's here is really good, and I'd love to hear more! Great work!
