First of all congrats for finishing a game with a new engine! The gameplay loop is there and the graphics get the job done conveying what's happening on screen. I played for some time but i was not able to try the bow unfortunately, because the curse never changed my weapon to that one! The thing that feels best is the effect of the goblin beaten to a pulp. The sword feels very weird collision-wise, it would be nice to have a bigger sword! The shield is interesting, but also a little weird, an interaction with spacebar to fling goblins would have been awesome!
To wrap things, the game is not very funny, but you made it all by yourself using new technology. It respected the theme. I'm sure you can do a lot better when you get the hang of it!
