I enjoyed playing your game, good work on a short jam - hope you had fun. I have some constructive commentary in the polish and entertainment sections from my playthrough below :)
Theme: I see what you're going for with the 'growing of weapons', it's an interesting play on the farming sim where you might exchange your coins for weapons, instead you cut out the middleman and grow them yourself.
Creativity: The most creativity was in the intro - your 'medieval-speak' was entertaining. However the gameplay itself did not showcase your creativity through unique elements.
Technical Achievement: Good work on this submission in only a 48hr jam - the game played well with no noticeable bugs.
Polish: I would love the option to skip/fast forward to the end of the day. Often, I had watered all my plants and half the day left to wait. I think a game such as this needs the opportunity to pause as well - I was able to pause it by clicking out of the player though. (Food for thought)
Entertainment: Solid, and enjoyable. However, I must say I was disappointed that there was no 'visual reward' for me as a player after the invasion. I would have loved to see a battle animation - even if you only had created one for a win and one for a loss. I felt as though just ticking over to the next invasion countdown made me feel like I'd wasted '13 days' worth of time.
Bonus Points: Easy to load, ran well, looks sharp. After the invasion my defence resets to zero, but I had 'just' harvested a bunch of plants! It would have been better for me as a player to wait an extra day and start off the second round with a full field being harvested instead of unnecessary overkill in the first round. I learned for the following invasion haha.
