I think it's a very cool concept, simple and neat designs and clear instructions! Perhaps if you'd still like to work on it, I would suggest that the difficulty pacing could be worked on, as having 8 elements might be too hard for a beginner. Maybe have an easy mode where there are only 4 or 5 elements to play around with. But overall, I like it and it fits the theme really well. Glad to hear that you've learnt a lot :)
