Thanks for playing our game and even more thanks for the praise! It was my friend who did the programming, and it truly is very impressive!
The characters really do appear tiny on the screen, and the 'doors' do blend in quite a bit of the wall, I can see how it can cause quite a bit of confusion. More playtesting probably would've really been useful as we were both used to staring at the art and didn't notice the sizing issues with the HUD either.
The move aspect was heavily DnD inspired and thought it made sense at the time, however I can see how to can get quite tedious after a while, thanks for pointing it out! The attack automatically misses if you don't select an enemy, however when you do it will attack every enemy in your attack range (the blue circle), it is a bit iffy and would've benefitted with better clarifications.
The instruction page is very lengthy and overwhelming, and it will be something to note for next time. It was a pretty ambitious idea but glad that the gameplay actually worked out in the end.
Thank you for the feedback, glad you enjoyed our game!
