The game is fun and well made so far. Wish you the best in developing it further. Love that the enemies can interact with each other
A few things to improve though:
1. Health items should be added, asap
2. The HP of the plants reduced a bit
3. A checkpoint system for the endless mode. Maybe every 5 levels. With the lack of HP replenishment, starting from scratch is a bit annoying.
4. The player model has a tendency to break. Head becomes detached from the body, arms, legs and torso glitching like crazy.
