Definitely could use some work in terms of smoothing out the user's experience interacting with the systems overall (UI is obviously the most prominent system in your game, so that'd take the priority), but it's also obvious that these things came as an extended result of overscoping, which I can definitely relate to. 

Don't let your expectations discourage you! Keep working on this and start by taking what's necessary to achieve your vision for what could have been made given the jam's time frame and then polishing it up. I'd love to see where you take this concept, personally.

Really cool concept and the gameplay was quite fun once I got the hang of it, until I got in range of the archers because they just killed me with no issues. nice game though and I can see a lot of potential

This is a really cool game from what I can see. I like the way that each monster has different attack pattern, special ability, and stats. I imagine this game has a lot of depth.I also like how you program each monsters movements each turn.

Unfortunately, the UI doesn't work too well which preventing me from playing that much of the game. 

As shown in the picture, I cannot scroll down to buy the cooler monsters.

Also, the menu kept overlapping with the action bar, as shown below, which made it impossible to program the enemy moves correctly, shown below.

I also wish that you could move your monster around in the starting grid location after you spawn them.

As is the game is hard to play because of the issues I mentioned above, but the game seems really fun and I would love to play this after the jam if some QOL improvements are added.
