great pacing for the game, all the upgrades feel meaningful.
the gem scaling for upgrades hits just right.
the mimic gamble is great, although i found there wasnt really a downside to it. the mimic still gave gold so you barely missed out
I got lucky with the final boss with 3 crits meaning i didnt even need to buy the last few HP upgrades.
I would love a longer sequel.
overall: 8/10 (would be 9 if it had some fitting music/sound effects)
