Pretty and clever puzzle game, I could see that expanded with even more brain-busting puzzles!

I also encountered several problems (that others already commented). The character sometimes refuses to come or enter a machine, and for level 5 I don't know what I am doing wrong but I can't seem to pass it. Maybe at least showing the player their wrong answer at the end to help them figure out what they did wrong would also help.

But appart from that, a really charming game. Well done!

Really cool game! I've rated almost 100 for the jam so far and this HAS to be in my top 5 for the concept, although I am a math guy so that helps lol. Art style is so cute kinda like my game with the hand drawn aesthetic.

Also, I know bugs have been pointed out, but I wanted to share mine with level 5 since it's telling me I got it wrong when I am pretty sure it's not.  I tried two solutions in case the splitter wasn't accounting for fractions but that didn't work either

this is a cool take on the theme! the little cube guy is cute too. i think the tutorial at the beginning doesn't really do a lot to help you understand what it wants from you, maybe some clues about the mechanical side of the game (for instance, highlighting the thing at the bottom to make it clear it's something you can pick up and move) would have been a better place to spend that time. i did still figure it out though and it was pretty fun seeing him get super big, especially when i messed up lol. great job overall!

I really enjoyed it! I was a bit confused at first, but I ended up getting the hang of it. Unfortunately, my game softlocked on level 4 or 5 (I'm not really sure). The character went through one of those scale machines and it didn't come out the other way :( . I still liked the game though, don't worry.

Really nice and intuitive. I like it!

Very nice, liked the use of Alex as a screen transition. Fairly intuitive design for connecting the pieces together, I might have appreciated an indication of Alex's number as it emerges from each device so I can track my progress more closely than just bigger or smaller.

Gosh, I'm impressed with the quality of this Jam and sure your game fits over the top notch group! 
Had fun with this game and the graphics totally nailed it!

Very clever and has a lot of potential! Looking forward to playing more! 

It is nice to see STEM-ish kind of game here. I liked the puzzles, but I couldn't finish the last one. I've built scheme as in picture and slime always disappears inside "3:1" block.

Really clever game! I love Alex

At first I thought this was an automation game, but nonetheless looks pretty neat, and if you resolve the bugs this can turn into a very enjoyable game.
