This game is very charming! Look at that cute green guy go! He moves SO smoothly!
So this game was a little rough on the puzzle design and a tiny on controls --honestly I recommend separating the jump button and the action buttons. It's usually clear enough what is to be done but it sometimes feels like you have to do it in ways that take more time than should be necessary--an example being that it seems you have to ride an elevator across two screens at least two or three times to solve the two-screen puzzle at the end of the demo.
It will be interesting to see how this expands when it gets into a more adventure-mode of game in terms of mobility options and puzzles alike--best of luck to you all, and I'm dropping a follow so I can see how it goes for you!
