A wonderful idea!
really interesting.
Visually, Quality/Resolution -wise, i think it's okay if you leave it as it is, however it would be a good idea to change the sprite's appearance to correspond to the weapon and armor upgrades. its hard to see a dagger sword and rapier all looking like the same thing.
BUT Gameplay- 6/10. this is very innovative idea, plus very simple. i'm sure many have thought of this before, actually, but the difference is that i can see it somewhat working here.
alright, [[i get that this game was probably made just as a guinea pig]] to test this one idea out, and that you guys have already brainstormed for if this develops into something bigger, {but i'd like to express my thoughts and ideas anyway.}
=1. a longer 'event bar'. having only one button to press, my choices are somewhat already restricted, it'd be nicer to have more events so that people can plan further ahead.
=2. i had a lot of trouble with the dragon, and it seems from the reviews that a lot of people did too. i tried to plan for this battle after i died by its hand, but then the dragon event changed from the previous play. if you need to include 'boss fights', you could set a permanent timer so gamers can plan their armor/weapons/items to suit it. otherwise it comes at us from outta nowhere and totally demolishes us.
its probably a guinea pig version of what you wanna do but you managed to show off that this COULD work. if you revamp it and make a trigger knight 2 i'd totally play it.
