I do not know how this has not got any ratings yet. It is a very polished puzzler with a great main mechanic that is expanded on really well! The mixing of colours made me grin as it makes so much sense and works so well. It was challenging throughout, but I think that the level where you had to jump between spikes was slightly unfair as after a few minutes I died and then had to completely reset progress. Maybe some sort of checkpoint system? Still, this is really great, I hope that you get the credit you deserve for it. Well Done!
