Thanks for playing the game!
For the abilities i wanted to have a sort of indicator flash up to how to use it and then revolve the level design on figuring out how it works (i.e. the cracked wall and the enemies behind it, to show the player it can kill enemies). but we had to focus on finishing the gameplay before polish
leading to a bit of weird bugs, but nothing game breaking at the very least
But yeah i agree with how the boss fight feels, due to making it within the last day we didn't really get to balance him out. because we were planning on some special effects to help indicate his attacks more clearly. as well as some sort of recharging shield if the fight was too difficult (kind of like holy mantle from Isaac), and the abilities to have more of a impact on the fight itself but we just kind of ran out of time.
and if time allowed i was gonna try and add some worldbuilding to the area because the game itself is inspired mostly of Hyper Light Drifter and Nuclear Throne. because i love the sort of desolate apocalyptic worlds where you have to interpret the story from the gameplay. but we mostly focused on it working first
Glad you enjoyed it!
