Really cool! I was a little confused at first what I was supposed to do - a tutorial might have been helpful, explaining what the different pieces do. However, I understand that having only 48 hours to develop the whole game means you probably prioritised adding 7 levels in, as opposed to 7 levels plus a tutorial. (Although, having 5 or 6 core levels instead of 7 may have been a worthwhile trade-off in order to squeeze in a tutorial? Take this with a grain of salt, as I don't know your development process haha. 😆)
The gameplay is really fun! It's challenging without being unfair (even though your pieces are randomly generated, you're able to strategically place them to combat the enemy pieces, so every piece is useful as long as you use it correctly!) It reminds me of chess, but real-time instead of turn-based. The graphics and audio are really nice too, it gives the game a very nice overall aesthetic. Fantastic job! 😄
