Thanks a lot for playing and the comment!
I have never made sprites and pixel art before. Most of the sprites are based on a Pokemon tile set I found online with some modifications. I am glad that you could recognise Boeing 747. That means my own drawings are not too bad :P
I am glad that you liked the push block puzzle. It is based on quantum gates and qubits, the building block of quantum computers! I only had to implement one type of gate. If more people like it, I may make a puzzle game just based on the quantum gates. Meanwhile, if you are interested in quantum computing, you can try the circuit composer on IBM Quantum Experience.
Last point, I really should have added a proper intro and little instructions on what is the point of the game. It's probably the biggest learning point for me in this jam.
