Thanks for playing our game! I agree with the speed in the end. While we play tested it we had a bit of back and forward with how fast you should be able to move while still feeling like you are moving from grid to grid. In the end we settled with what we submitted but you can hold down the forward and backwards key to move continuously (while still taking a small pause between movements).
I think we learned a lot being involved with this jam and what we could do more to bring it inline with the genre while still offer our take on the game.
