Interesting puzzles. I like those kind of games. For me as a colorblind the colors haven't been ideal and additional symbols on the block would've helped. But besides that I really enjoyed it :)
Thanks for playing! Sorry I don't have much experience with accessibility in games, I will definitely try incorporate it into future games.
No problem in a gamejam. You've got limited time. That's something to consider when you plan on creating your first bigger one 😉
