I love how creative this is! I managed to get through the entire game, though you certainly gave my brain a good wrangling!

The presentation was great, gameplay was solid, levels were well thought out, and overall was an awesome concept.

My biggest criticism is definitely the lack of music and SFX. Even stock sound effects would've been enough (for future reference, you can get 100% free sounds from freesound.org), though music is understandably a harder one to source, though even some ambience would've brought this to life.

I get part of the challenge is remembering which side your key and plunger is on, though maybe some kind of indicator that isn't in your face would've been helpful.

Awesome work my guy!

The art is nice. I only wish there was an indicator on which side the key is.

The game is very well created. The art is amazing. I always struggle  when I have to understand witch face I will need :D

Cool concept and good difficulty ramp-up!

Wow! Really cool concept and nice looking game! Really enjoyed it! Quite challenging!

Love the unique concept and cool presentation! Steep learning curve but really enjoyable :) Good job!

Idea is quite unique, well done on that part.

Controls feel nice as well, feels a bit easy to learn hard to master, which never is something bad.

Feel free to try out our game as well :)

Game has a very steep learning curve, but the animation of cube moving is nice, especially sliding down the stairs! The mechanic including a plunger is quite confusing tho :/
