Can you solve it without clues and spoilers?

Someone had a hard time completing our first level and I understand that. It is a real tester so I added clues and spoilers in the description on itch. Can you solve it without them? If not, are they good? All kinds of feedback on the game is also appreciated, it is our second ludum dare so we have much to learn :)
