This is an ay-ok game:
I wish the player didn't fall down so fast, as the very snappy movement can sometimes be hard to predict/time.
And I am not sure is this was intentional or a bug, but the checkpoints don't work ( which makes it really annoying when you die ).
The difficulty is good, and the ladders work nicely ( they gave me a feeling of safety, as I could use them to rise up extremely fast ). But, I feel maybe just one or two more gimmicks could have added a lot of depth ( a falling or switching platform, spring, etc. ).
I am glad you controls are properly listed in the description and actually has a breifing ( making them easier to see), although I would recommend using bold for and centering it, usingt it as a header to make the control list even clearer.
The graphics work for this type of game, nothing hurted my eyes here unlike some games in the jam, and the player character is very cute!
I do feel that if the graphics matched the player this game would look way better- but it's definitely fine ( games like Dadish and Super Cat Tales don't look too good, but the consistent style really pulls them together in terms of visuals ).
To explain this a little further, if a game uses thick outlines for the characters, then the tiles should also have the same thick outlines, and even the backgrounds but to a lesser extent ( more advanced artsists don't always use this limitation on all assets, but they still take it into consideration ).
Overall:
For your first game jam game, and having it only made in two days, you did really well!
Don't follow all the advice people give you, just make sure to check and see what works for you ( not all advice give is for you, but rather it might be for the people making the video ).
I've seen a lot inexperienced, and insincere people giving advice online, so be careful ( if a video/post says something like "You need to do this", "You're doing everything all wrong", or "This way is worse" then stay away from it. )
