Don't know if this was your intention making the game, but I found this to be pretty funny to play. Like you said I just trust my guts and pray to RNGesus after placing my bets lol. It could have been fun to have had a high scores leaderboard to see how much money players can get.
The music was nice, but a bit too loud imo and there was no options to turn it down or off. Would also have liked to see something QoL features like speed up fights or more sound effects.
Overall a pretty nice "autobattler" game, if you can call it that. But I enjoyed it for what it is noenetheless.
