Pointy End

I moved Left as my first move at the beginning because I didn't understand who I was. It'd be nice to have some kind of indicator that displays for a few seconds, lol.

However, the more I've gotten into this game, I'm really digging the Stephen's Sausage Roll style! I think this could be developed more with larger maps and SSR-like Sokoban objectives instead of only squaring off with enemies.

I don't know if you plan to further develop the game or not but two other things come to mind apart from the starting player indicator:

1. I think gameplay could go faster if the enemies moved at the same time. I find myself feeling a bit impatient waiting for the enemy movement animations to play out. Or maybe sped-up animations might be nice.
2. A key delay when entering the next level would be nice. I wasn't sure if I needed to be on the uppermost tile of the ramp in the upper-right, so I would press Up again and that would make me immediately move up in the next level.
3. I feel like the chests should be a bonus and that your total score should be Rooms Passed + Chests Collected to get a truly accurate high score.

This game could be really cool with further developments, like coins from enemies to spend at an occasional shop with permanent ammo upgrades, purchasable health, or a speed potion that lets you move twice for one turn!
