Short but i really liked the concept, i would've liked different levels for example a different map in the interior where you can't shoot arrows to high or they will hit the roof or a map where you play in the middle and have to keep both sides away. I also think the bow isn't used often, an enemy that doesn't move and that you have to shoot with the bow would give it more uses.
Crazy good for a free game! It's amazing how professional it looks as well as how you can see the inspirations of the game influencing its design, ah! I love it so much and I can't wait to see when it'll be completed, so well done! The only thing keeping me from making it a full 5 stars is due to the crashing bug that happens for no reason but seeing as it isn't complete, very understandable!
Overall a really good game that just needs a bit more fleshing out- I know that probably won't happen since you've moved on to making assets for other devs, which is perfectly reasonable, but the game goes from fairly detailed and fun to stupidly hard by the end and with a non-ending. I think a full version of this is something people would gladly pay for though, and it could easily be something I'd buy as one of the best games on this site, comparable to the best games on steam if it got more development.
