Thanks for the honest review!
yeah the lack of tutorial really hurts the game, since the mechanics are a bit complex, but I did my best to write up the rules. I actually went back and added some tutorial gifs, hopefully new players will see them!
Yeah, trying to find the niche is difficult... Another comment called it an assault course game which is weirdly accurate. I did plan on adding a deck building aspect (hence the deck button) but I ran out of time to even implement more card types. People seem to like the game, though, so I guess thats the next step if I keep going.
