Yes, Scratch is acceptable. You can use whatever engine you want.
As for your second question, that defeats the point. The point is to create something within the interim of the duration, making it in advance ruins the fun and tbh the spirit of the jam.
I love everything about this game. The puzzles are challenging and involve very clever solutions. You should consider building on this mechanic some more, I’d love to see where you go with this.
Moreover, I can see this getting a homepage on speedrun.com because oh boy, this feels like a great game to run. And on that note, I feel like I have discovered a fun little exploit that will allow Any% runners to reach the exit in… less than intended ways. I recorded a clip for you! https://youtu.be/CN8LLdd0JtY
Essentially, it involves resizing the player using the zoom feature, so much that the player clips beyond the bounds of the level and hitting the exit collider. Please don’t patch this lol this is great.
Seriously though, great submission, it’s a shame I can’t rate since I didn’t participate but you get a solid 10/10 from me.
EDIT: You should also consider adding a standalone version so I can play it offline too. WebGL is great and all but requiring a browser to play a game with such great potential is a bit of a downer.
I really enjoy this concept and the art is beautiful.
However my biggest criticism is the feel of the controls. Movement feels a bit too... rigid, and the collision hitboxes are very unforgiving. There were times where I died when my character didn't even touch any spikes.
I definitely sense some inspiration from Portal and maybe even... Stanley Parable if I had to guess? Love that
