I've played some Card Games before (Yugioh and Hearthstone, but mostly Yugioh) so seeing this game was interesting!
I think having a simple 'Click the Toaster to Continue' floating UI, and some text to remind the Player what Phase they are in would make for better readability. Maybe some text to show the odds of upgrading a card as well :3
I still had fun with this one! Nice stuff :3
