Hi there ^^
Thanks for the compliment! Its true that the roll doesn't have invincibility frames, and for one the time restriction is the cause for this. But yer know, since it does add that certain extra speed it does come in handy :D
The game is best to be played if all the available combat options are being used cleverly. There's 3 rooms in the game which you gotta battle enemies in. There ain't a boss, but each room has new enemies, which might not be enough to go through it again, but feeling the gameplay and soundtrack is enough to get myself back to it, haha (not to be proud here)
Glad you liked it :D
