This is a clever spin on the game of chess! I thought going in that it would be pretty similar to standard chess, but it feels completely different! Being able to advance a pawn across the entire board in one move feels illegal - witch makes it very fun!
One thing that confused me was why I couldn't move certain pieces sometimes. I think adding a popup under the mouse when you try to move a piece that says "not enough points!" would clarify that, and you could even also fade out the pieces that you can't afford to move this turn, just so the player knows. This prevents the awkward situation where you go to move a piece, and... nothing happens.
Aside from that I think this is a nice spin on regular chess, and it would definitely be fun to play with friends!
