i really love how hempuli just straight up takes small ideas that dont really need 3 hour long gameplay to be good, i wish i could make good games or straight up just make games. but only got sprites and music, also what engine did you use?
Oh yeah, I totally forgot to actually answer the question, whoops! As RedPipe implied, this was made using Clickteam Fusion 2.5 and its HTML5 export addon. It's a janky engine but more powerful than one would expect at first glance.
