I love this game. The graphics are simple but charming, the style really speaks to me 10/10 for me here. The mechanics are also solid, simple and fun.
There are only minor downsides, but I'll list them here anyway:
- can't upgrade unit directly from shop, need to clear inventory space first
- games are relatively short, would be nice to set a game time for X rounds or X wins (at least 15 or 20 wins should be an option)
- Tier 1 & 2 units are fewer in number than Tier 3 units, but it's also really hard to get more than 1 or 2 Tier 3 units before winning. The game would gain a lot from a greater selection of early units, rather than late units. (maybe T2s could share some of their upgrades, rather than having 2 unique ones each)
