You did a good job with all the mechanics and spawning system, but you kept it very small, (endless, top down...)which is probably for the best.

But I still appreciate your Work

Good thing that the tutorial is clear. :) (On the other hand, I had some trouble with Replit’s interface at first, but then I solved it. X))

I like the transparent trail effect (I intended to add one in another game of mine, actually, to show movement in the past).

Apparently, a good strategy is not being near the edges when a key touches a lock, as one may appear where you are!

Small bug: I had a freeze once, at score 18 when my character was at the edge of the screen, but I could not replicate it.

I managed to reach 47. The principle is simple but works. :) Suggestion to extend the game: it would surely be interesting to manage to give some functionality to the locks, such as closing a door or something else, while they are up.

Winner of the jam!

This is really cool!
