Great first jam game! The beginnings of platformer are definitely here, and it has some cool aesthetic choices. I think my only gripe is that there's two or three really cheap jumps on the second level, but other than that was alright~

This is really pretty basic.

There are several flaws in the management; overall a good project.

But ... It may sound a little rude, but in this form it’s difficult to put the game "fun" rate: it is short and therefore does not bother; while there are no catchy solutions.

And maybe platformers is just not mine.

(And forgive my English, I use a Google Translate due to lack of knowledge of the language)

Fun platformer! By mistake jumped over the second checkpoint on the first level, barely missed the spikes and almost had a heart attack. Would keep playing if there were more levels :)

Since it is not needed maybe the mouse could be hidden.
