Challenging, but very fun! I loved the strategy you needed in this game - planning out routes to take and seeing them work out was real satisfying. The variety of sound effects was great too, and it really stopped them from getting repetitive. One thing would be to point out the mechanics a bit more clearly, since I didn't realise you could move against walls until I was decently into the game. It was still a nice little game, though, and great work!
