Love boss fights in Undertale, so this game hooked me right away. The bosses are varied and immediately show what kind of attacks to expect. The restraint mechanics actually affect the character during combat, which is great.
The only issue I ran into was a softlock when I tried to remove the blindfold (I tested it 2–3 times in a row). Also, the bosses don’t seem to be arranged by difficulty - the last one was surprisingly too easy in terms of attacks and the amount of restraints.
