I really like this one! The pixel art looks great and the controls feel really good which is hard for a game just using the mouse. A few small suggestions...
- You can setup your game on itchio to start automatically without needing the user to click run game. always good to remove barriers from the player.
- Put a little effort into your start screen. You already have some great art to use, just draw it big, like an animation of the player running. Instead of just Click to Start, make it say the name of your game "Polar Bear Jam". You can click to start smaller below that if you want, or put your name there instead.
- I like how it shows the text of how to play in game. You might even do that more by first bringing the player through some obstacles that dont require the super jump to get them used to that. Then show them how to use the super jump.
- Maybe add something to avoid? Thin ice you have to run over.
- Try adding something to the background. The easiest way is taking a look at the Sky object in the platformer example and tweaking it to suit your game
- There is a little texture bleeding in some of the sprites. There are a few ways t o fix that, the easiest is to setTileFixBleedScale(.5) which will crop half a pixel from around every sprite. Another better way is to add 1 pixel of padding around your sprites and use the padding setting of the tile function. The platformer demo was recently updated to include this. it's pretty minor though, just something you can fix if you want to..
Great work! You can always continue building it and adding more stuff to extend the level. I'll be keeping an eye on how it develops!
