Very good and polished game. Nice SFX and music. Looks awesome. Nice that you had time for palettes as well. Game fits the theme really well.
I really enjoyed it and I played for quite a while. For me, it was pretty hard, so I pretty much always chose the re-minder, but the other upgrades were also really good and really helped killing the monsters. Overall great submission! It felt really nice when there was only one tile left, and it was about to be destroyed, but you got a re-minder and created more.
